Description

Technical Field

[0001] The utility model relates to the technical field of automobile ceiling manufacturing, in particular to an automobile ceiling fabric composite device. Background Art

[0002] As an important part of the vehicle interior, the car ceiling plays an indispensable role in improving the competitiveness of the car. Its function is also changing. It not only improves the decoration of the car interior, but also requires the ceiling to have good heat insulation and thermal insulation effects, as well as reduce the noise inside the car and improve the sound absorption effect. After the semi-finished product of the car ceiling injection molding (ceiling frame) is processed, it is necessary to attach a layer of fabric to its lower surface. The fabric layer is located inside the car body and mainly plays a decorative and sound insulation role.

[0003] The bonding of the ceiling frame and the fabric is mainly achieved by applying glue and then pressing and bonding through a pressing mold. In order to better ensure a smooth and firm bonding, the current fabric bonding process generally pre-applies glue to the ceiling frame, then transfers it to the bonding mold, then places the fabric to be bonded on top of the ceiling frame, and finally closes the mold; since glue is easy to harden, in order to ensure a firm bond, a heating module is generally set in the bonding mold in the prior art, which is conducive to the heating module heating the ceiling frame during the bonding process, driving the pre-applied glue on the ceiling frame to melt, thereby ensuring that the fabric can be fully bonded to the ceiling frame during bonding.

[0004] In the prior art, the heating module is directly embedded in the composite mold, which is not only difficult to install, but also greatly increases the manufacturing cost of the composite mold. In addition, the embedded heating module is inconvenient to maintain later, and the composite mold needs to be disassembled. In addition, after repeated disassembly and assembly of the composite mold, the upper and lower mold positions are prone to inaccurate problems, which ultimately affects the flatness of the composite fabric.

[0026] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See also Figures 1 to 4 As shown, an embodiment of the present application discloses a composite device for automobile ceiling fabric, comprising an upper mold frame 1 and a lower mold frame 2, wherein the upper mold frame 1 is provided with an upper module 3 which can be lifted vertically, and the lower mold frame 2 is provided with a lower module 4 for placing and positioning the ceiling frame, and the lower mold frame 2 is also provided with a baking component for heating the ceiling frame, the baking component is slidably connected to the lower mold frame 2 in a horizontal direction, and the lower mold frame 2 is also provided with a driving component for driving the baking component to reciprocate between a baking position and an initial position.

[0028] In the above structure, when the ceiling frame pre-coated with glue is placed on the lower module 4 and positioned stably, the driving component drives the baking component to move from the initial position to the top of the upper module 3, and the baking component heats and bakes the ceiling frame to activate the glue on the ceiling frame, and then the baking component is reset to the initial position; then the fabric is placed on the upper surface of the ceiling frame manually or by a robot or an automatic feeding mechanism, and the upper module 3 moves downward to close the mold, driving the fabric and the ceiling frame to be compositely bonded together. The upper mold frame 1 is pre-installed with a cylinder unit (not shown in the figure) for driving the upper module 3 to rise and fall.

[0029] In this embodiment, the driving component includes a motor unit 5. Specifically, the motor unit 5 includes a servo motor and a reducer.

The outer ends of the two output shafts 6 are connected to driving gears 7; the lower end of the baking component is connected to two spaced-apart racks 8, and the two racks 8 are respectively meshed with the two driving gears 7. Under the drive of the motor unit 5, the two output shafts 6 rotate synchronously, driving the two driving gears 7 to rotate, thereby driving the two racks 8 to move horizontally, and finally realizing the back-and-forth movement of the baking component between the initial position and the baking position, realizing baking and heating of the ceiling frame.

[0030] In addition, in the above structure, a horizontally arranged and rectangular mounting base 9 is connected to the lower mold frame 2, and the lower module 4 is installed at one end of the mounting base 9 and is located directly below the upper module 3; both sides of the mounting base 9 in the width direction are also provided with linear guide rails 10 extending along its length direction and parallel to each other, and the lower end of the baking component is connected to two groups of linear sliders 11 respectively connected to the two linear guide rails 10 for sliding connection, and the structural arrangement of the linear slider 11 and the linear guide rail 10 fully ensures the stability of the horizontal movement of the baking component with low noise.

The cross bar 13 structure effectively increases the structural strength between the two mounting plates 12, thereby ensuring stable translation of the entire baking assembly.

[0032] More specifically, in this structure, the mounting base 9 includes a rectangular frame, and a mounting base plate is connected to the lower surface of the mounting base plate near one end of the upper module 3, and there is a certain height difference between the upper surface of the mounting base plate and the upper surface of the frame; the motor unit 5 is connected to the mounting base plate and is located in the middle position of the width direction thereof, so that the driving gears 7 at both ends of the two output shafts 6 are respectively engaged under the two racks 8, making the layout of the entire driving structure more reasonable.
