[0002] Currently, during the manufacturing process of car seats, a seat cover is wrapped around a foam component and sewn together to form the seat body. However, due to sewing errors or compression of the foam component, the seat cover and the foam component do not fit tightly together, resulting in wrinkles on the cover. Such car seats do not meet factory requirements.

[0003] The existing technology requires manual ironing of wrinkled areas on the seat surface to ensure a tight fit between the foam and the seat cover. However, due to the heavy weight of the seat, manual ironing requires the collaboration of multiple people, requires water and electricity, and heat from the iron, leaving limited room for movement, making contact and burns more likely. Furthermore, manual inspection after ironing is highly subjective, leading to errors in judgment and the release of defective products. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1 、 3 The utility model provides an automatic ironing tool for the surface of a car seat, comprising an off-line tool fixing fixture 1 and an automatic ironing robot 2. The off-line tool fixing fixture 1 and the automatic ironing robot 2 are respectively located on both sides of the assembly line, the off-line tool fixing fixture 1 is located on the back side of the seat, and the automatic ironing robot 2 is located on the front side of the seat. A fixing mechanism is provided on the upper part of the off-line tool fixing fixture 1. When the seat reaches the automatic ironing station after the seat positioning tool follows the assembly line, the fixing mechanism fixes the seat positioning tool so that the seat and the seat positioning tool will not shake left and right. An ironing mechanism 21 and an industrial camera 22 are provided on the top of the automatic ironing robot 2. After the ironing mechanism 21 irons the entire seat, the industrial camera 22 takes a picture, and then the automatic ironing robot 2 analyzes and checks the wrinkles, and the ironing mechanism 21 irons the wrinkles again.

[0021] For details, please refer to Figure 2 The fixing mechanism includes a base plate 11, a spline mounting plate 12, four splines 13, a retraction cylinder 14, two guide rails 15 and two sliders 16. Two splines 13 are fixed on both sides of the bottom surface of the base plate 11, and two guide rails 15 are fixed on both sides of the upper surface of the base plate 11. The guide rails 15 are slidably connected to the sliders 16, and the sliders 16 are fixed to the bottom surface of the spline mounting plate 12. The sliders 16 can slide on the guide rails 15, so that the spline mounting plate 12 slides on the guide rails 15 together with the sliders 16. Two splines 13 are fixed on both sides of the spline mounting plate 12, and the bottom surface of the retraction cylinder 14 is fixed in the middle of the rear of the base plate 11. The end of the upper movable part of the retraction cylinder 14 is connected to the spline mounting plate 12. The retraction cylinder 14 pushes and pulls the spline mounting plate 12, so that the two splines 13 on the spline mounting plate 12 are retracted and extended. When the splines 13 are extended, the splines 13 press the seat positioning tooling, so that the seat positioning tooling and the seat will not shake left and right.

[0022] Specifically, strip holes 121 are provided on the front and rear parts of both sides of the spline mounting plate 12 , and screws pass through the strip holes 121 to fix the spline 13 . The spline 13 can be adjusted left and right on the spline mounting plate 12 according to different tooling.

[0023] For details, please refer to Figure 4-5A mounting plate 221 is fixed on the side of the industrial camera 22, and the mounting plate 221 is connected to the top of the automatic ironing robot 2. The automatic ironing robot 2 controls the industrial camera 22 to fly and acquire images, and then uses a visual algorithm to perform depth analysis on the images to find the wrinkles. The ironing mechanism 21 includes a mounting plate 211 and an iron 212. The mounting plate 211 can drive the iron 212 to rotate flexibly under the control of the automatic ironing robot 2, which is convenient for ironing different curved surfaces. The mounting plates 211 are fixed on both sides of the mounting plate 221 and are located below the top of the automatic ironing robot 2. The iron 212 is fixed on the bottom of the mounting plate 211.

[0024] Specifically, two connecting rods 2112 are connected to the left and right sides of one side of the middle of the second mounting plate 211, and a spring 2111 is sleeved on the connecting rod 2112. The arrangement of the connecting rod 2112 and the spring 2111 makes the second mounting plate 211 stretch up and down with specific elasticity, thereby driving the iron 212 to stretch up and down for good ironing. A rotating block 2114 is provided on the lower part of the second mounting plate 211 near the side of the connecting rod 2112. The rotating block 2114 is connected to the lower part of the second mounting plate 211 through an axis. The rotating block 2114 can rotate around the axis, thereby driving the rotating block 2114 and the iron 212 below it to rotate together. The second mounting plate 211 is far away A rotating rod 2115 is provided at the lower portion of one side away from the rotating block 2114. A spring 2111 is sleeved on the rotating rod 2115. Rollers 2113 are connected to both sides of the bottom of the rotating rod 2115. The rotating rod 2115 and the rollers 2113 rotate slightly together with the rotating block 2114, causing the iron 212 to rotate along with it, making it easier to iron different curved surfaces. A connecting plate 2116 is provided at the bottom of the second mounting plate 211. The bottom surface of the connecting plate 2116 is fixed to the iron 212. One side of the top of the connecting plate 2116 is fixed to the bottom surface of the rotating block 2114, and the rollers 2113 on the other side are in contact with the top of the connecting plate 2116.

[0025] Specifically, a solenoid valve 222 is fixed on the side of the industrial camera 22 . The solenoid valve 222 is located below the mounting plate 1 221 . The solenoid valve 222 is connected to the iron 212 . The solenoid valve 222 supplies air to and exhausts air from the iron 212 .

[0026] For details, please refer to Figure 6 A light source 223 is provided on the bottom surface of the industrial camera 22. When taking pictures, the light source 223 is hit on the seat cover, so that the industrial camera 22 can clearly take pictures.

[0027] The movement principle of the present invention is: when the seat moves along the assembly line on the seat positioning tooling, the seat flows to the ironing station. At this time, the off-line tooling fixing fixture 1 extends the inserting gear 13 under the action of the contraction cylinder 14 to press the seat positioning tooling, so that the seat positioning tooling and the seat will not shake left and right. The automatic ironing robot 2 starts to control the iron 212 to iron the seat cover. After the ironing is completed, the automatic ironing robot 2 controls the industrial camera 22 to take a flying shot to acquire an image, and then performs in-depth analysis through a visual algorithm to find the wrinkled part. After finding it, the information is given to the automatic ironing robot 2, and the automatic ironing robot 2 controls the iron 212 to automatically iron the part.

[0028] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
