Description

Technical Field

[0001] This application relates to the field of automotive interior processing technology, and in particular to an automotive nappa leather headliner covering device and its manufacturing method. Background Technology

[0002] Currently, the headliner is an important component of the overall car interior. Its main function is to enhance the aesthetics of the vehicle's interior. Simultaneously, the headliner improves heat insulation and reduces noise levels inside the vehicle; it also enhances sound absorption and improves passenger comfort and safety. Traditional headliners use knitted or non-woven fabrics as decorative materials, resulting in a lower level of sophistication and a less premium feel. Nappa leather, through a special wrapping technique, becomes the headliner trim layer, significantly elevating the overall quality of the car's interior and meeting customers' personalized needs.

[0003] In the existing technology, the operator first cuts the genuine leather fabric and sews it together according to the shape of the car roof. There is a layer of cotton between the genuine leather fabric and the roof. The three are connected by PUR hot melt adhesive. The operator attaches the cotton and genuine leather fabric to the car roof in sequence. After the bonding is completed, the excess part of the genuine leather fabric is cut off according to the shape of the car roof.

[0004] Regarding the aforementioned technologies, the use of manual bonding methods can easily lead to misalignment and surface wrinkles, especially at the edges of the roof. Manual pressing can cause uneven fabric tension, resulting in wrinkles and curling edges. Subsequent operations require operators to cut the fabric according to the shape of the roof. Manual cutting can lead to insufficient or excessive cutting in certain areas, necessitating repeated cutting or replacement of the fabric for re-bonding and cutting. This results in low efficiency for car roof wrapping. Summary of the Invention

[0005] To improve the efficiency of car headliner wrapping, this application provides a car nappa leather headliner wrapping device and its manufacturing method.

[0006] In a first aspect, this application provides an automotive nappa leather headliner covering device, which adopts the following technical solution:

[0007] A car Nappa leather headliner covering device includes a first conveyor belt, a second conveyor belt, and a processing device. The processing device is located between the first and second conveyor belts. The first conveyor belt is used to convey fabric to the processing device, and the second conveyor belt is used to transport the processed headliner. The processing device includes an adsorption component, a bonding component, a fixing component, an adhesive component, and a cutting component. The bonding component is located on the side of the first conveyor belt closer to the second conveyor belt and is used to tightly bond the fabric to the adsorption component. The adsorption component is located between the first and second conveyor belts and is used to adsorb the fabric. The fixing component is located between the bonding component and the second conveyor belt and is used to fix the headliner and transport the bonded headliner. The adhesive component is located on the side of the fixing component away from the adsorption component and is used to bond the fabric and the headliner frame. The cutting component is located inside the adsorption component and is used to cut the fabric.

[0008] By adopting the above technical solution, conveyor belt one conveys genuine leather fabric to the processing device, conveyor belt two conveys the processed car roof, the adsorption component initially adsorbs the fabric on conveyor belt one, the bonding component and the adsorption component work together to make the fabric and the adsorption component fit tightly together, the fixing component is used to support the roof frame, the adsorption component conveys the fabric into the fixing component, the cutting component cuts the fabric, the bonding component makes the fabric and the roof frame fit tightly together, after the bonding is completed, the fixing component conveys the car roof onto conveyor belt two, which improves the efficiency of car roof wrapping.

[0009] Optionally, guide blocks are fixed on both sides of the upper end of conveyor belt one along the width direction. The guide blocks are arranged along the length direction of conveyor belt one. A limiting plate is fixed on the upper end of conveyor belt one along the width direction. The limiting plate is located on the side of the guide block closer to conveyor belt two. The side of the guide block closer to the limiting plate is hollow. A second vacuum pump is fixed inside the guide block. Exhaust pipes are connected to the sides of the two guide blocks that are far apart. Several vacuum pipes are provided on the sides of the guide blocks that are close together. The several vacuum pipes are arranged along the length direction of the guide block and are connected to the guide block. The vacuum pipes are slidably connected to the guide block along their own length direction. Several movable plates are provided inside the guide block. The movable plates correspond one-to-one with the vacuum pipes. The movable plates are fixedly connected to the lower end of the vacuum pipes and are slidably connected to the guide block along the width direction of the guide block. Several first electric telescopic rods are provided inside the guide block. The first electric telescopic rods correspond one-to-one with the movable plates. The first electric telescopic rods are arranged along the width direction of the guide block. The two ends of the first electric telescopic rods are fixedly connected to the movable plates and the guide blocks, respectively.

[0010] By adopting the above technical solution, the guide block guides the fabric, ensuring that the fabric is conveyed in a consistent orientation. The limiting plate blocks the fabric, ensuring that the fabric is ultimately in the same position on the conveyor belt. Because the fabric is relatively soft, wrinkles will occur along its long side. The first electric telescopic rod, in conjunction with the moving plate, moves the suction pipe closer to the fabric. When the suction pipe contacts the fabric, the second suction machine, in conjunction with the suction pipe, adsorbs the fabric. The first electric telescopic rod retracts, bringing the fabric into the specified shape. The exhaust pipe is used to expel the air drawn into the guide block, improving the convenience of fabric shape adjustment.

[0011] Optionally, the adsorption component includes a slide rail, a horizontal moving component, a lifting component one, an adsorption block, and a first air extractor. The slide rail is located between conveyor belt one and conveyor belt two and is fixedly connected to the ground in the horizontal direction. The lifting component one is located above the slide rail and is slidably connected to the slide rail in the length direction of the slide rail. The horizontal moving component is located above the slide rail and is used to drive the lifting component one to slide in the length direction of the slide rail. The adsorption block is connected to the lifting component one, and the lifting component one is used to drive the adsorption block to move vertically. The adsorption block is hollow. The first air extractor is fixedly connected to the inside of the adsorption block. The adsorption block has several openings. The first air extractor and the adsorption block work together to adsorb the fabric. The upper end of the adsorption block is connected to an air guide pipe.

[0012] By adopting the above technical solution, the horizontal moving component is used to drive the lifting component to move along the length of the slide rail. The lifting component drives the adsorption block to move downward and fit against the genuine leather fabric. The first air pump works with the port to adsorb the fabric, and the air duct is used to exhaust the air, which improves the convenience of fabric adsorption.

[0013] Optionally, the bonding component includes a sponge block and a second lifting component. The second lifting component is located between the first conveyor belt and the second conveyor belt and is located on the side of the first conveyor belt away from the first lifting component. The sponge block is connected to the second lifting component and is located directly below the adsorption block.

[0014] By adopting the above technical solution, when the adsorption component adsorbs the fabric, the lifting component 2 drives the sponge block to move upward. When the sponge block moves upward and comes into contact with the fabric, the sponge block deforms, thereby making the fabric and the adsorption block fit tightly together, which improves the adsorption effect of the adsorption block on the fabric.

[0015] Optionally, the fixing components include a bracket, several baffles, a rectangular block, a fixing rod, a lifting component, and a lever. The bracket is located between the sponge block and the conveyor belt and is fixedly connected to the ground. Several baffles are located at the upper end of the bracket and are arranged circumferentially along the bracket. Two baffles along one length of the conveyor belt are slidably connected to the bracket vertically, and two baffles along one width of the conveyor belt are fixedly connected to the bracket. A sliding opening is vertically opened at the upper end of the bracket. The rectangular block is located above the bracket and directly opposite the sliding opening. The rectangular block is slidably connected to the bracket vertically. The fixing rod is located below the bracket and is fixed to the two baffles along one length of the conveyor belt. The conveyor belt is connected and hinged vertically to the rectangular block. The lifting component three is located between the sponge block and the bracket. The lifting component three is used to drive the fixed rod to move vertically up and down. There are two springs between the fixed rod and the rectangular block. The two springs are located on both sides of the fixed rod along the width direction. The two ends of the springs are fixedly connected to the rectangular block and the fixed rod respectively. The lever is fixedly connected to the ground vertically and faces the rectangular block. There are several rollers rotatably connected to the side of the two baffles that are close to each other along the width direction of the conveyor belt. The rollers are arranged along the length direction of the baffles. There is a driving component on the side of the two baffles that are opposite to each other. The driving component is used to drive all the rollers to rotate.

[0016] By adopting the above technical solution, the bracket supports the roof frame, and multiple baffles and rectangular blocks work together to place the roof frame in the same position on the upper end of the bracket. When the fabric is bonded to the roof frame, the lifting component three works with the fixed rod to drive the two baffles and rectangular blocks to move downward. The rectangular blocks pass through the sliding opening and contact the lever. When the rectangular blocks rotate, the cut fabric falls from above the rectangular blocks. Two springs work together to keep the rectangular blocks in a horizontal state. At this time, all the rollers of the drive component rotate, thereby conveying the car roof to the conveyor belt two, which improves the convenience of car roof recycling.

[0017] Optionally, several support rods are provided vertically between conveyor belt one and conveyor belt two. The support rods are all fixedly connected to the ground and arranged around the circumference of the support frame. Several hot air guns are fixedly installed on the side of the support rods near the support frame. The hot air guns are arranged vertically.

[0018] By adopting the above technical solution, the support rod supports the hot air gun, and the hot air gun activates the hot melt adhesive on the back of the fabric and the surface of the frame, thereby improving the bonding effect between the fabric and the ceiling frame.

[0019] Optionally, the cutting component includes several cutting blades, a moving block, and a second electric telescopic rod. The lower end of the adsorption block has a moving opening. The second electric telescopic rod is fixedly connected vertically inside the adsorption block and faces the moving opening. The moving block is fixedly connected to the lower end of the second electric telescopic rod. Several cutting blades are fixedly connected to the lower end of the moving block and are arranged circumferentially along the moving block. All cutting blades are located inside the moving opening and are slidably connected vertically to the adsorption block.

[0020] By adopting the above technical solution, the second electric telescopic rod drives the moving block to move downward, and the moving block drives multiple cutting blades to pass through the moving opening and cut the fabric. The cut fabric falls onto the upper surface of the rectangular block, which improves the convenience of fabric cutting.

[0021] Optionally, the bonding components include a lifting component four, a connecting block, a chain, several moving motors, several gears, a connecting rod, and a roller. The lifting component four is located between the sponge block and the conveyor belt two, and is directly opposite the support. The connecting block is connected to the lower end of the lifting component four and is directly opposite the support. The chain is located inside the connecting block and is slidably connected to the connecting block along its circumference. Several moving motors are located between the lifting component four and the connecting block. The moving motors are arranged vertically and connected to the lifting component four. The gears correspond one-to-one with the moving motors. The gears are coaxially fixedly connected to the output shaft of the moving motors. Several gears mesh with the chain. The connecting rod is fixedly connected to the lower end of the chain. The roller is rotatably connected to the end of the connecting rod away from the chain.

[0022] By adopting the above technical solution, when the fabric is attached to the ceiling frame, the lifting component four drives the connecting block to move downward. When the roller contacts the fabric, the moving motor and gear work together to drive the chain to move circumferentially along the connecting block. The movement of the chain drives the connecting rod to move, which in turn drives the roller to fix along the surface of the fabric, further compacting the fabric and improving the stability of the fabric bonding.

[0023] Secondly, this application provides a method for manufacturing a car Nappa leather headliner, comprising the following steps:

[0024] Material pretreatment: Place nappa leather in a plasma treatment device, use argon gas as a medium, and treat for 60-90 seconds at a power of 200-300W to enhance surface activity. Apply adhesive to the back of the nappa leather and then cool it.

[0025] Material delivery: The sponge block ensures that the nappa leather fits tightly against the absorbent material and delivers it to the top of the support.

[0026] Adhesive activation: A hot air gun is used to heat the back of the nappa leather and the surface of the skeleton to activate the adhesive's tack.

[0027] Material bonding: Adhesive components ensure a tight fit between the nappa leather and the skeleton;

[0028] Material cutting: The cutting part trims off excess nappa leather;

[0029] Material conveying: The lifting component three cooperates with the fixed rod to move two of the baffles downward, and the driving component drives the roller to rotate, thereby conveying the canopy onto the conveyor belt two.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. Conveyor belt one conveys genuine leather fabric to the processing device, conveyor belt two conveys the processed car headliner, the adsorption component initially adsorbs the fabric on conveyor belt one, the bonding component and the adsorption component work together to make the fabric and the adsorption component fit tightly, the fixing component is used to support the headliner frame, the adsorption component conveys the fabric into the fixing component, the cutting component cuts the fabric, the bonding component makes the fabric and the headliner frame fit tightly, after the bonding is completed, the fixing component conveys the car headliner to conveyor belt two, which improves the efficiency of car headliner wrapping.

[0032] 2. The guide block guides the fabric, ensuring it is conveyed in a consistent orientation. The limiting plate shields the fabric, ensuring it remains in the same position on the conveyor belt. Due to the fabric's softness, wrinkles may occur along its long side. The first electric telescopic rod, in conjunction with the moving plate, brings the suction pipe closer to the fabric. When the suction pipe contacts the fabric, the second suction machine, in conjunction with the suction pipe, adsorbs the fabric. The first electric telescopic rod retracts, bringing the fabric to the desired shape, thus improving the ease of fabric shape adjustment.

[0033] 3. The bracket supports the roof frame. Multiple baffles and rectangular blocks work together to place the roof frame in the same position on the upper end of the bracket. When the fabric is bonded to the roof frame, the lifting component three works with the fixed rod to drive two horizontally distributed baffles and rectangular blocks to move downward. The rectangular blocks pass through the sliding opening and contact the lever. When the rectangular blocks rotate, the cut fabric falls from above the rectangular blocks. Two springs work together to keep the rectangular blocks in a horizontal state. At this time, all the rollers of the drive component rotate, thereby conveying the car roof to the conveyor belt two, which improves the convenience of car roof recycling.

Because the fabric is relatively soft, wrinkles will occur along its long side. The first electric telescopic rods 17 and the movable plates 16 work together to bring the suction pipe 15 closer to the fabric. When the suction pipe 15 contacts the fabric, the second suction machine 13 works with the suction pipe 15 to adsorb the fabric.

The sponge block 32 is connected to the lifting component 21 and is located directly below the adsorption block 24. When the adsorption component adsorbs the fabric, the lifting component 21 drives the sponge block 32 to move upward. When the sponge block 32 moves upward and comes into contact with the fabric, the sponge block 32 deforms, thereby making the fabric and the adsorption block 24 adhere tightly, improving the adsorption effect of the adsorption block 24 on the fabric.

The two springs 48 cooperate to keep the rectangular block 43 in a horizontal state. The lever 46 is fixedly connected to the ground vertically and faces the rectangular block 43. The rectangular block 43 moves down through the sliding opening 47 and contacts the lever 46. The lever 46 pushes the rectangular block 43 to flip, so that the cut fabric falls from above the rectangular block 43. Two baffles 42 set along the width direction of conveyor belt 1 are rotatably connected to the side of their proximity. The multiple rollers 491 are arranged along the length direction of the baffles 42. A driving member 49 is provided on the side of the two baffles 42 facing away from each other. All the rollers 491 of the driving member 49 rotate, thereby conveying the car roof to the second conveyor belt 7, which improves the convenience of car roof recycling.

[0058] The implementation principle of the automotive Nappa leather headliner covering device in this application embodiment is as follows: The operator places the leather fabric on the conveyor belt 1 for conveying. The first electric telescopic rod 17 and the moving plate 16 cooperate to drive the suction pipe 15 to adsorb the leather fabric, so that the fabric is in a predetermined shape. The adsorption block 24 adsorbs the leather. When the adsorption block 24 adsorbs the fabric, the lifting component 31 drives the sponge block 32 to move upward. When the sponge block 32 moves upward and comes into contact with the fabric, the sponge block 32 deforms, thereby making the fabric and the adsorption block 24 fit tightly together. At this time, the adsorption block 24 moves to the top of the bracket 41. The hot air gun 81 heats the hot melt adhesive on the back of the leather fabric and the surface of the headliner frame to activate the adhesion. The adsorption block 24 descends to make the fabric fit with the headliner frame. During the fitting process, the cutting component 6 cuts off the excess leather fabric. After cutting, the adsorption block 24 moves away from the car roof. The lifting component 41 drives the connecting block 52 to move downward. When the roller 57 contacts the fabric, the moving motor 54 and gear 55 work together to drive the chain 53 to move circumferentially along the connecting block 52. The movement of the chain 53 drives the connecting rod 56 to move, which in turn drives the roller 57 to fix along the surface of the fabric and further compact the fabric. After compaction, the lifting component 3 45 works with the fixing rod 44 to drive two baffles 42 and rectangular blocks 43 to descend. The lever 46 pushes the rectangular blocks 43 to flip, so that the cut fabric falls from above the rectangular blocks 43. At this time, all the rollers 491 of the drive component 49 rotate, which in turn transports the car roof to the conveyor belt 2 7. This process does not require manual intervention, which improves the accuracy and efficiency of fabric bonding and cutting, and thus improves the efficiency of car roof wrapping.
