Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing, and in particular to a non-woven fabric hemming machine for automobile roof. Background Art

[0002] In car interiors, non-woven fabrics are used to decorate the ceiling, which not only improves the comfort and aesthetics of the car, but also enhances the functionality and durability of the ceiling. When wrapping the non-woven fabric on the car ceiling, a small section of non-woven fabric needs to be reserved at the edge, and then the reserved non-woven fabric is folded upwards and wrapped around the edge to cover the entire ceiling.

[0003] However, when the existing roof covering fabric is used, adhesive is used to adhere and fix the edge fabric. After the adhesive is applied to the car roof, the non-woven fabric and the car roof need to be squeezed to spread the adhesive and expand the adhesive area, so that the adhesive between the non-woven fabric and the car roof can completely and firmly adhere the non-woven fabric to the car roof. The existing equipment cannot ensure that the adhesive is fully bonded between the car roof and the non-woven fabric after applying the adhesive, resulting in some adhesive not being flattened and making the non-woven fabric uneven after solidification, which leads to uneven edges of the car roof, further affecting the subsequent installation of the car roof, resulting in the car roof being unable to fit the car frame firmly. In addition, the unflattened adhesive will also cause the non-woven fabric to be unable to be firmly fixed on the car roof, which is easy to cause the non-woven fabric to loosen during subsequent use, and then the problem of non-woven fabric warping occurs, which reduces the processing quality of the car roof and affects the appearance of the car.

[0045] like Figure 1 , Figure 2 , Figures 10 to 12 As shown, a cloth feeding assembly for automatically replacing and feeding the non-woven fabric 5 is provided on the side plate 2, and the cloth feeding assembly includes a side rod 51 symmetrically fixedly connected between the two side plates 2, and a plurality of upper and lower symmetrical conveying rollers 52 are evenly arranged on the side rod 51, and the conveying rollers 52 are driven to rotate by an external driving device, and the driving device is preferably a motor, and the conveying rollers 52 are in contact with the edges of both sides of the non-woven fabric 5, and a feeding port 53 is provided on the side plate 2, and the non-woven fabric 5 can pass through the feeding port 53, and a plurality of traction rollers 54 symmetrically distributed up and down are rotatably connected inside the feeding port 53, and the traction rollers 54 are driven by an external driving device, and the driving device is preferably a motor, and the traction rollers 54 can clamp and pull both sides of the non-woven fabric 5;

[0046] like Figure 2 , Fig.10 and Fig.11 As shown, the cloth feeding assembly also includes two cutting groove frames 55 symmetrically fixedly connected to the bottom of the side rod 51, a slide groove frame 56 corresponding to the position of the cutting groove frame 55 is fixedly connected to the side rod 51, a slider 57 is slidably connected to the slide groove frame 56, a cutting knife 58 is rotatably connected to the bottom of the slider 57, and a groove matching the cutting knife 58 is opened on the cutting groove frame 55, and the cutting knife 58 can move in the groove on the cutting groove frame 55.

[0047] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments:

[0048] The initial state is: the gear 48 is meshed with the teeth at the bottom of the gear rod 46, the slider 57 is at the outermost side of the slide slot frame 56, the cutting knife 58 is at the outermost side of the groove of the cutting slot frame 55, the telescopic shaft of the electric telescopic rod 61 is not extended, and the storage box 62 is at the highest position. When used for the first time, the non-woven fabric 5 is inserted from the feeding port 53 on the right side panel 2. First, the non-woven fabric 5 will contact the traction roller 54 in the right feeding port 53. Figure 1 and Figure 2 At this time, the traction roller 54 is started to rotate, and the traction roller 54 rotates to pull the non-woven fabric 5 through the upper and lower conveying rollers 52. The conveying roller 52 guides the non-woven fabric 5 to move, and the non-woven fabric 5 continues to move and enters the feeding port 53 in the left side panel 2, as shown in FIG. Figure 2 The nonwoven fabric 5 is on the left side of the viewing angle shown in the figure, and contacts the traction roller 54 in the left feeding port 53, thereby completing the limiting and fixing of the nonwoven fabric 5.

[0049] The cloth feeding component delivers the nonwoven fabric 5:

[0050] The staff pushes or pulls the two sliders 57 to move, so that the sliders 57 slide on the slide frame 56. When the sliders 57 move, they drive the cutting knife 58 to move in the groove on the cutting frame 55. When the cutting knife 58 moves, it cuts the non-woven fabric 5. The cutting knife 58 cuts the non-woven fabric 5. Because the distance between the two sliders 57 is fixed, the quantitative cutting effect is achieved, avoiding unevenness during conventional manual cutting, and preventing the non-woven fabric 5 from being unable to effectively cover the automobile roof panel due to insufficient cutting.

[0051] The hemming component wraps the non-woven fabric 5 onto the roof panel of the automobile:

[0052] Although the conveying roller 52 supports both sides of the non-woven fabric 5, it does not fix the non-woven fabric 5. After the non-woven fabric 5 is cut, it will fall onto the bottom mold 43 under the action of gravity. Then the staff will place the car roof panel that needs to be covered with the non-woven fabric 5 in the bottom mold 43. The car roof panel will fit the bottom mold 43 and squeeze the non-woven fabric 5 so that the non-woven fabric 5 can fit the bottom of the car roof panel. At this time, the electric cylinder 42 is started. After the electric cylinder 42 is started, its telescopic shaft extends to drive the bottom mold 43 to move upward. When the bottom mold 43 moves upward, the frame plate 45 on it will move upward. After the frame plate 45 moves upward, it will contact the bottom of the grooving frame 55. When the frame plate 45 cannot continue to move upward after contacting the grooving frame 55, the electric cylinder 42 continues to move upward and will drive the bottom mold 43 to squeeze the spring. Spring 44, spring 44 will be compressed, at this time the bottom mold 43 gradually approaches the frame plate 45, in this process, because the toothed rod 46 is limited by the frame plate 45 and cannot move, the boss 47 will drive the gear 48 inside it to move upward during its continued upward movement, and the gear 48 rotates under the meshing action of the toothed rod 46, and the gear 48 drives the edging rod 49 to swing upward, and the edging rod 49 drives the spring telescopic rod 491 and the edging strip 410 to swing upward, and in the process of the edging strip 410 rotating upward, it will first contact the bottom of the edge of the non-woven fabric 5, and the edging strip 410 continues to swing upward so that the edge of the non-woven fabric 5 is folded upward to make it tilted at a certain angle, which is done to make the edge of the non-woven fabric 5 tilted to form a shielding to prevent the glue from flowing out of the edge to the outside after subsequent gluing, and then close the electric cylinder 42.

[0053] The glue trimming kit applies glue to the edges of the car roof panels:

[0054] After the electric cylinder 42 is closed, the electric telescopic rod 61 is started again. After the electric telescopic rod 61 is started, it drives the storage box 62 fixed on its telescopic shaft to move downward, and the storage box 62 drives the structures arranged thereon to move downward. When the storage box 62 gradually approaches the top of the bottom mold 43, the electric telescopic rod 61 is closed, and the output shaft of the electric telescopic rod 61 stops extending. At this time, the guide block 69 and the cutting knife 6116 are not in contact with the car roof board, and the resistance wheel 610 will contact with the car roof board. Then the electric control valve on the discharge port of the guide block 69 is opened, so that the adhesive is discharged from the discharge port of the guide block 69. Because the feed pipe 63 is externally connected to the raw material pump, the adhesive will enter the storage box 62 through the feed pipe 63 under the action of the raw material pump, and the adhesive in the storage box 62 enters the annular member 613. The adhesive in the annular member 613 enters the discharge port of the guide block 69 through the connecting pipe 612. Finally, the glue enters the discharge head 691 from the discharge port of the guide block 69, and then the servo motor 65 is started. The output shaft of the servo motor 65 drives the rotating rod 66 to rotate, and the rotating rod 66 drives the guide block 69 in the movable groove 67 to rotate synchronously. Under the elastic action of the spring 2 68, the guide block 69 always contacts the inner surface of the guide frame 64, and the guide block 69 will fit the shape of the guide frame 64 and slide inside the movable groove 67. Because the shape of the guide frame 64 is the same as the shape of the edge of the automobile roof, the guide block 69 can adapt to the edge shape of the guide frame 64 and displace. When the guide block 69 moves, it can drive the discharge head 691 to move synchronously, and the discharge port of the above-mentioned guide block 69 releases glue through the discharge head 691. When the discharge head 691 moves, the glue will be discharged along the moving trajectory of the discharge head 691, so that the glue is squeezed on the edge of the upper surface of the automobile roof panel on the bottom mold 43. In addition, when the discharging head 691 follows the rotation of the rotating rod 66, it will drive the contact wheel 610 to move synchronously. At this time, the contact wheel 610 will roll on the car roof board. When the contact wheel 610 rolls to the raised part of the car roof board, the contact wheel 610 will move upward on the raised part of the car roof board. The contact wheel 610 drives the discharging head 691 to move upward in the guide block 69. At this time, the discharging head 691 will compress the spring three 692. Since the edges of most car roof boards have uneven positions, when the contact wheel 610 rolls to the concave or raised part of the car roof board, under the elastic reset of the spring three 692, the discharging head 691 moves downward or upward, so as to adapt to the edge of the special-shaped car roof board and effectively apply the glue to the edge of the car roof board. The automatic glue squeezing method avoids the problem of inaccurate manual glue squeezing. Uniform glue squeezing can prevent the loose adhesion caused by too little manual glue squeezing, and can also prevent the situation of glue overflow caused by too much manual glue squeezing.

[0055] When the rotating rod 66 rotates one circle, the glue coating process is completed, and the electric control valve on the guide block 69 is closed at this time, so that the discharge port in the guide block 69 stops discharging glue.

[0056] The hemming assembly allows the edge material of the non-woven fabric 5 to hem the automobile roof panel:

[0057] Then the electric cylinder 42 is started again, so that the telescopic axis of the electric cylinder 42 extends upward, the electric cylinder 42 continues to drive the bottom mold 43 to move upward, the bottom mold 43 continues to compress the spring 1 44, at this time the distance between the frame plate 45 and the bottom mold 43 gradually decreases, the bottom mold 43 continues to drive the boss 47 to move upward, the boss 47 continues to move upward so that the gear 48 inside it continues to move upward, the gear 48 continues to rotate under the meshing action of the gear rod 46, the gear 48 drives the edge rod 49 to continue to swing upward, the edge rod 49 drives the edge strip 410 through the spring telescopic rod 491 to continue to fold the edge material of the non-woven fabric 5, The stretchable effect of the spring telescopic rod 491 allows the edging strip 410 to effectively fit the edge of the automobile roof panel, and due to the stretchable effect of the spring telescopic rod 491, it can adapt to the concave or convex position on the automobile roof panel. At the same time, because the edging strip 410 is made of soft rubber material, the edge of the non-woven fabric 5 is completely folded over and fits the upper surface of the automobile roof panel. At this time, the edge of the non-woven fabric 5 can contact the adhesive, and the adhesive can be stretched under pressure through the extrusion of the edging strip 410, without the need for manual secondary flattening of the adhesive, so that the non-woven fabric 5 can be effectively fitted and wrapped on the automobile roof panel.

[0058] The glue coating and trimming component cuts the excess edge material of the non-woven fabric 5:

[0059] After the binding strip 410 is bound and pressed against the non-woven fabric 5 for a period of time, the adhesive dries, and the adhesive is adhered and fixed to the edge of the non-woven fabric 5 after drying. At this time, the electric telescopic rod 61 is started again, and the telescopic shaft of the electric telescopic rod 61 extends to drive the storage box 62 to move downward. The storage box 62 continues to move downward, which will drive the structure on it to move downward. The guide block 69 in the movable groove 67 moves downward, and the guide block 69 drives the friction wheel 610 to move downward through the discharge head 691. The friction wheel 610 will move downward on the top of the car. Under the interference of the roof board, the discharge head 691 moves upward in the guide block 69 and continues to compress the spring three 692 again. At this time, the cutting knife two 6116 will conflict with the non-woven fabric 5 folded on the roof board of the automobile. At this time, the servo motor 65 is started, and the output shaft of the servo motor 65 drives the rotating rod 66 to continue to rotate. The rotating rod 66 drives the sliding sleeve 6111 to rotate synchronously. The sliding sleeve 6111 drives the knife holder 6115 to move synchronously through the stabilizing rod 6113. The knife holder 6115 drives the cutting knife two 6116 moves and cuts on the edge of the non-woven fabric 5. At this time, the second cutting knife 6116 is fixedly connected to the guide block 69 due to the sliding sleeve 6111, so that the second cutting knife 6116 moves in the same motion trajectory as the above-mentioned discharging head 691. When the second cutting knife 6116 moves to the raised part of the automobile roof plate, the second cutting knife 6116 is resisted by the raised part of the automobile roof plate and moves upward. The second cutting knife 6116 makes the knife holder 6115 move upward and compresses the spring 4 611 4. When the second cutting knife 6116 moves to the concave part of the automobile roof panel, the knife holder 6115 moves downward under the elastic reset action of the fourth spring 6114, and the knife holder 6115 drives the second cutting knife 6116 to move downward, so that the second cutting knife 6116 always moves in accordance with the shape of the automobile roof panel. The second cutting knife 6116 can cut off the excess edge material of the non-woven fabric 5, thereby achieving the effect of automatically cutting off the edge material and avoiding the influence of excessive edge material on the subsequent installation of the automobile roof panel.

[0060] The cloth feeding component replenishes the nonwoven fabric 5:

[0061] After the above operations are completed, the equipment returns to its initial state and takes the finished car roof panel out of the bottom mold 43. At this time, the traction roller 54 and the conveying roller 52 are driven to rotate simultaneously by an external driving device. When the traction roller 54 and the conveying roller 52 rotate simultaneously, the non-woven fabric 5 can be conveyed from the feeding port 53 into between the two side panels 2. At this time, the non-woven fabric 5 can continue to cover the top of the bottom mold 43, thereby achieving the effect of automatically replenishing the non-woven fabric 5, reducing the steps required for manual replenishment, and improving the overall operation efficiency.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
