Description

Technical Field

[0001] This invention belongs to the field of automotive headliner fabric processing technology, specifically relating to a device for laminating automotive headliner fabric and a substrate. Background Technology

[0002] The headliner is an important part of the overall car interior. Its main function is to enhance the aesthetics of the car interior. At the same time, the headliner can also improve the heat insulation between the car and the outside, reduce interior noise, improve sound absorption, and enhance the comfort and safety of passengers.

[0003] In existing automotive headliner production lines, after applying adhesive to the headliner fabric, it is manually flipped to bond the adhesive-coated side to the headliner substrate. A thermoforming mold is then used to heat-press the fabric and substrate together. Because current products are quite large, exceeding 2 meters in length and 1.3 meters in width, manual flipping requires two people simultaneously. Furthermore, during manual flipping, adhesive drips or splashes onto the surrounding environment, such as the floor, walls, equipment, and even workers' clothing. This not only incurs high labor costs but also reduces the adhesion between the headliner fabric and substrate due to adhesive drips or splashes, ultimately leading to product defects. Summary of the Invention

[0004] The present invention provides a bonding device for automotive headliner fabric and substrate, which aims to bond the adhesive surface of the headliner fabric to the headliner substrate.

[0005] A laminating device for automotive headliner fabric and substrate includes a frame, an upper support and a lower support on the frame, a conveyor belt arranged horizontally on the upper support, on which headliner fabric is placed, a lower substrate on the lower support, on which headliner substrate is placed, and the downstream drop end of the conveyor belt is located on the displacement path of the lower substrate driving the headliner substrate.

[0006] Another object of the present invention is to provide a method for flipping and laminating automotive headliner fabric, comprising the following steps:

[0007] A. Lay the canopy fabric with the adhesive side facing up flat on the conveyor belt of the upper support.

[0008] B. Control the telescopic frame to raise the placement plate, place the canopy substrate on the placement plate, and then adjust the height adjustment mechanism to control the placement plate to be in the initial receiving position below the conveyor belt;

[0009] C. The conveyor belt carries the canopy fabric to the downstream drop end. When the canopy fabric hangs down naturally from the downstream drop end of the conveyor belt and comes into contact with or near the upstream end of the canopy substrate on the placement plate, the translation drive mechanism drives the drag frame to move towards the upstream end of the conveyor belt.

[0010] D. When the translation drive mechanism drives the drag frame to move forward until the ceiling fabric completely covers the ceiling substrate, the translation drive mechanism drives the drag frame to return to the initial receiving position.

[0011] E. Pick up the composite component of the ceiling substrate and ceiling fabric and transfer it to the hot pressing mechanism for hot pressing.

[0012] In the above solution, a canopy fabric with adhesive coating on its back and the adhesive side facing up is placed on the conveyor belt, and a canopy substrate is placed on the lower base plate. The adhesive side of the canopy substrate and the canopy fabric is arranged facing up. The conveyor belt transports the canopy fabric backward, and the lower base plate reciprocates along the lower support to ensure that the adhesive side of the canopy fabric and the canopy substrate are evenly covered, so that the adhesive side of the canopy fabric naturally covers the adhesive side of the canopy substrate, ensuring that the adhesive side of the canopy fabric and the adhesive side of the canopy substrate can be covered, reducing labor costs while improving production efficiency.

[0016] Example 1

[0017] like Figures 1-3 The apparatus shown is a laminating device for automotive headliner fabric and substrate, comprising a frame, an upper support 10 and a lower support 20 on the frame, a conveyor belt 11 arranged horizontally on the upper support 10, on which headliner fabric A is placed, and a lower substrate 21 on the lower support 20, on which headliner substrate B is placed, with the downstream drop end of the conveyor belt 11 located on the displacement path of the lower substrate 21 driving the headliner substrate B.

[0018] In the above scheme, a canopy fabric A with adhesive coated on its back and the adhesive side facing upwards is placed on the conveyor belt 11, and a canopy substrate B is placed on the lower substrate. The adhesive side of the canopy substrate B and the canopy fabric A are arranged facing upwards. The conveyor belt 11 transports the canopy fabric A downstream. The downstream drop end of the conveyor belt 11 is located on the displacement path of the canopy substrate B driven by the lower substrate 21. When the canopy fabric A naturally falls from the downstream drop end of the conveyor belt 11 of the upper support 10 to contact or be close to the front end face of the canopy substrate B on the lower substrate 21, the lower substrate 21 drives the canopy substrate B to move. The displacement direction of the canopy substrate B is opposite to the transmission direction of the conveyor belt 11. Therefore, the canopy substrate B and the canopy substrate A are displaced. The adhesive surface of ceiling fabric A contacts the substrate B, allowing it to naturally cover the surface to be bonded. Furthermore, ceiling fabric A gradually spreads out over the substrate B, preventing it from being folded or partially covered. This improves the bonding quality and efficiency between the adhesive surface of ceiling fabric A and the substrate B, facilitating the next step of transferring the pre-bonded ceiling fabric A and substrate B to a hot press for hot pressing.

[0019] The preferred lower substrate 21 includes a horizontally arranged shelf 211 for placing the ceiling substrate B and a drag frame 212 that moves horizontally on the lower support 20.

[0020] In the above scheme, the ceiling substrate B is placed on the placement plate 211. The placement plate 211 is moved by the drag frame 212 on the lower support 20. The placement plate 211 and the conveyor belt 11 are arranged close to each other in the vertical direction, so as to prevent the ceiling fabric A from slipping off the conveyor belt 11 at the end of the material drop, and ensure that the adhesive surface of the ceiling fabric A and the adhesive surface of the ceiling substrate B can be completely covered.

[0021] The preferred shelf 211 and the drag frame 212 are connected by a vertical height adjustment mechanism 30.

[0022] In the above scheme, a vertical height adjustment mechanism 30 is provided between the storage plate 211 and the towing frame 212. The height adjustment mechanism 30 can be a lifting cylinder, a hydraulic lift, etc. The height of the storage plate 211 is adjusted by the height adjustment mechanism 30 to facilitate the loading and unloading of the ceiling substrate B and the contact with the adhesive surface of the ceiling fabric A. When the storage plate 211 starts to move, the height adjustment mechanism 30 lifts the storage plate 211, further making the storage plate 211 and the conveyor belt 11 close together in the vertical direction, ensuring that the adhesive surface of the ceiling fabric A and the adhesive surface of the ceiling substrate B can be completely covered.

[0023] Furthermore, the towing frame 212 is connected to a translation drive mechanism 22, which drives the towing frame 212 to reciprocate linearly on the lower support 20. The lower support 20 has rails 23 on both sides, and the towing frame 212 is set on the rails 23. The translation drive mechanism 22 drives the towing frame 212 to reciprocate linearly along the rails 23.

[0024] Furthermore, the translation drive mechanism 22 is one of a gear and rack mechanism, a lead screw and nut slider mechanism, a cylinder, a chain drive mechanism, or a belt drive mechanism. The toothed belt 221 in the translation drive mechanism has its two ends connected to the opposite sides of the drag frame 212, and the belt body of the toothed belt 221 passes over the power toothed pulley of the drive motor 24 and the reversing toothed pulley on the support roller 25. The drag frame 212 is located between the power toothed pulley and the reversing toothed pulley.

[0025] The drive frame 212 performs reciprocating linear motion on the lower support 20. The translation drive mechanism 22 drives the drive frame 212 to move towards the upstream end of the conveyor belt 11 to receive the gradually falling ceiling fabric A. The translation drive mechanism 22 drives the drive frame 212 to return to the initial receiving position and delivers the composite of ceiling substrate B and ceiling fabric A.

[0026] The preferred height adjustment mechanism 30 is a scissor-type lifting bracket. The upper end of the height adjustment mechanism 30 is connected to the shelf 211, and the lower end is fixed to the towing frame 212. The scissor-type lifting bracket in the above solution has a high load-bearing capacity, which makes the lifting of the shelf 211 more stable.

[0027] Example 2

[0028] A method for flipping and laminating automotive headliner fabric includes the following steps:

[0029] A. Lay the canopy fabric A, with the adhesive side facing up, flat on the conveyor belt 11 of the upper support 10.

[0030] B. Control the height adjustment mechanism 30 to raise the placement plate 211, place the ceiling substrate B on the placement plate 211, and then adjust the height adjustment mechanism 30 to control the placement plate 211 to be in the initial receiving position below the conveyor belt 11.

[0031] C. The conveyor belt 11 carries the canopy fabric A to the downstream drop end. When the canopy fabric A hangs down naturally from the downstream drop end of the conveyor belt 11 and comes into contact with or near the upstream end of the canopy substrate B on the placement plate 211, the translation drive mechanism 22 drives the drag frame 212 to move towards the upstream end of the conveyor belt 11.

[0032] D. When the translation drive mechanism 22 drives the drag frame 212 to move forward until the ceiling fabric A completely covers the ceiling substrate B, the translation drive mechanism 22 drives the drag frame 212 to return to the initial receiving position.

[0033] E. Pick up the composite of the ceiling substrate B and the ceiling fabric A and transfer it to the hot pressing mechanism for hot pressing.

[0034] This invention controls the placement plate 211 to be in the initial receiving position below the conveyor belt 11 by adjusting the height adjustment mechanism 30. The conveyor belt 11 carries the canopy fabric A to the downstream dropping end. When the canopy fabric A hangs down naturally from the downstream dropping end of the conveyor belt 11 and comes into contact with or is close to the upstream end of the canopy substrate B on the placement plate 211, the translation drive mechanism 22 drives the drag frame 212 to move to the upstream end of the conveyor belt 11. This avoids the phenomenon of localized wrinkles of the canopy fabric A covering the surface to be bonded on the canopy substrate B or localized omissions. It improves the bonding quality and bonding efficiency of the adhesive surface of the canopy fabric A and the surface to be bonded on the canopy substrate B, so as to carry out the next step of transferring the pre-bonded canopy fabric A and the canopy substrate B to the hot pressing mechanism for hot pressing.

[0035] Preferably, in order to ensure that the adhesive surface of the canopy fabric A and the adhesive surface of the canopy substrate B can be completely and smoothly covered, the travel speed of the conveyor belt 11 and the translation drive mechanism 22 are the same.
