Description

Technical Field

[0001] The present invention belongs to the intersecting technical field of textile machinery and automobile parts production equipment, relates to automobile interior decoration manufacturing automation equipment, and specifically relates to automobile roof fabric feeding and matching equipment. Background Art

[0002] The soft fabric required for a car roof needs to be pressed onto the curved car roof frame. Currently, before pressing the soft fabric (fabric surface + adhesive surface) onto the car roof frame, the curvature of the soft fabric must be adjusted to match the car roof frame. Traditional processes rely on manual labor or semi-automatic equipment, which presents the following problems:

[0003] (1) Insufficient bending adaptation: Soft fabrics need to be bent along the length direction to match the curvature of the car roof frame, but manual adjustment is inefficient and has poor precision, which can easily lead to wrinkling or degumming after pressing.

[0004] (2) Difficulty in controlling tension: Soft fabrics must be evenly stretched in the width direction, otherwise they will deviate or become loose during transportation.

[0005] (3) Adhesion of the adhesive surface: The clamping jaws are in direct contact with the adhesive surface and are prone to adhesion, thus interrupting production.

[0006] (4) Process fragmentation: Fabric conveying, flipping, lifting, and bending adjustment are completed by multiple devices, which is inefficient and causes cumulative positioning errors.

[0007] (5) The conveying time is too long: Traditional fabric conveying relies on separate conveying equipment, which is too slow and affects the efficiency of the production line. Summary of the Invention

[0147] According to the present embodiment, a car roof fabric feeding and matching device is provided, which is used to adjust the curvature of a rectangular soft fabric in the length direction to match the curvature of the car roof frame so as to press it onto the car roof frame.

[0148] Therefore, the automobile roof fabric feeding and matching equipment of this embodiment has the following beneficial effects:

[0149] (1) The three-stage telescopic mechanism (first telescopic mechanism, second telescopic mechanism, and third telescopic mechanism) realizes a large range of displacement in the x-axis, significantly improves the displacement speed, and improves the transmission speed and production efficiency of the production line.

[0150] (2) Double rows of grippers synchronously control the Y-axis ends of the soft fabric to ensure the fabric is flat.

[0151] (3) The bending control mechanism independently adjusts the multi-point z-direction height of the soft fabric in the x-axis direction on both sides to accurately match the curvature of the skeleton.

[0152] (4) The first telescopic mechanism, the second telescopic mechanism, the third telescopic mechanism, the tensioning mechanism, the lifting mechanism, the bending control mechanism and the clamping mechanism are controlled by the controller to operate in coordination, thereby improving production efficiency.

[0153] Furthermore, two tensioning mechanisms are provided, each movably mounted on the first telescopic mechanism along the y-axis. The tensioning mechanisms follow the first telescopic mechanism's telescopic movement along the x-axis. A controller controls the two tensioning mechanisms to move away from each other along the y-axis, thereby driving the two rows of clamping jaws indirectly mounted thereon to move away from each other along the y-axis, thereby tightening the soft fabric they clamp. This arrangement effectively addresses fabric slack along the y-axis and prevents wrinkles from forming during subsequent pressing.

[0154] Furthermore, there are two lifting mechanisms, one mounted on each tensioning mechanism and capable of rising and falling along the z-axis. A controller controls the two lifting mechanisms to rise in tandem relative to the tensioning mechanism along the z-axis, thereby raising the two rows of clamping jaws mounted on the tensioning mechanism a certain distance along the z-axis to elevate the soft fabric being clamped. This arrangement allows the soft fabric to be raised to the desired height for subsequent lamination, separating horizontal and vertical motion to minimize interference.

[0155] Furthermore, two second telescopic mechanisms are respectively provided on the lifting mechanism and can be extended and retracted along the x-axis. A controller controls the two second telescopic mechanisms to coordinately stretch along the x-axis relative to the lifting mechanism, thereby causing the soft fabric material clamped by the two rows of clamping mechanisms indirectly provided thereon to move. Two third telescopic mechanisms are respectively provided on the second telescopic mechanism and can be extended and retracted along the x-axis. A controller controls the two third telescopic mechanisms to coordinately stretch along the x-axis relative to the second telescopic mechanism, thereby causing the soft fabric material clamped by the two rows of clamping mechanisms directly and indirectly provided thereon to move. This arrangement has the following beneficial effects:

Such a setting has the following beneficial effects: (1) the z-axis height of each point on both sides of the soft fabric can be independently controlled, and any curved surface can be generated according to actual needs; (2) the screw transmission has high precision and is suitable for high curvature skeletons.

[0158] Furthermore, the clamping mechanism includes a pair of clamping jaws and corresponding clamping jaw cylinders. The clamping jaw cylinders are used to drive the opening and closing of the pair of clamping jaws. The clamping jaw cylinders are connected to a controller and thus controlled by it. Among the pair of clamping jaws, one of the clamping jaws located on the lower side in the z-axis direction is provided with a plurality of ejectors. The ejectors are arranged along the x-axis direction. When the clamping mechanism clamps the soft fabric, the ejectors are used to penetrate the adhesive surface of the soft fabric to prevent the glue on the fabric from directly adhering to the clamping jaws. Such an arrangement has the following beneficial effects: (1) the ejectors prevent the adhesive surface from adhering to the clamping jaws, reducing downtime for cleaning; (2) ensuring the stability of continuous production.

[0159] Furthermore, the automobile roof fabric feeding and matching equipment further includes a fabric conveying and flipping mechanism provided on a conveyor line for conveying soft fabric fabrics, wherein the soft fabric fabrics conveyed on the conveyor line are in a state where the fabric surface is facing downward and the adhesive surface is facing upward, and the fabric conveying and flipping mechanism is used to flip the soft fabric fabrics to a state where the fabric surface is facing upward and the adhesive surface is facing downward and transfer the fabrics to between two rows of clamping mechanisms along the x-axis direction, and the controller includes a third control unit and a fourth control unit, wherein the third control unit is used to control the operation process of the fabric conveying and flipping mechanism, and the fourth control unit is used to coordinately control the operation process of the first telescopic mechanism, the second telescopic mechanism, the third telescopic mechanism, the tensioning mechanism, the lifting mechanism, the bending control mechanism, and the clamping mechanism.
