[0002] The sunroof guide rail rubber strip is a key component ensuring the sunroof's sealing, waterproofing, and smooth operation. Its material, installation process, and maintenance directly affect the user experience. To ensure a tight fit between the rubber strip and the sunroof frame, it needs to be pressed down using a pressing device during installation.

[0003] For example, an automatic sunroof sealing strip pressing device disclosed in CN212499021U includes an equipment frame and an automatic pressing mechanism disposed on the side of the equipment frame. The automatic pressing mechanism includes a mounting bracket connected to the equipment frame. A positioning plate is horizontally extended from the upper end of the mounting bracket toward the inner side of the equipment frame. A pressing cylinder is disposed on the positioning plate. The pressing cylinder extends downward through the positioning plate and extends a retractable pressing telescopic rod. A pressing roller is connected to the lower end of the pressing telescopic rod.

[0004] However, the aforementioned rubber strip pressing device can only press the rubber strip longitudinally. Since most rubber strips are made of elastic material, their edges are prone to deformation and bounce when pressed longitudinally, affecting the sealing performance of the rubber strip installation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2The automatic pressing device for the car sunroof guide rail rubber strip in this embodiment is characterized by: including a frame 3, a limiting mechanism 2 is provided in the middle of the frame 3 for limiting and fixing the sunroof guide rail, a pressing mechanism 1 is provided on the upper inner side of the limiting mechanism 2 for pressing the rubber strip, the pressing mechanism 1 includes a translation mechanism 105, a moving platform of the translation mechanism 105 is fixedly connected to a moving frame, a pair of lifting cylinders 101 are symmetrically arranged on both sides of the top of the moving frame, the piston rod of each lifting cylinder 101 is fixedly connected to a rubber-coated wheel clamping mechanism 103 for rolling the rubber strip in all directions, and a lifting guide rail 102 is provided on the side wall of the moving frame facing the rubber-coated wheel clamping mechanism 103, and adjacent rubber-coated wheel clamping mechanisms 103 are slidably connected to the lifting guide rail 102. During pressing, the operator places the left and right sunroof guide rails on top of the limiting mechanism 2, which then limits the guide rails. The rubber strip is then placed on the guide rails and clamped and fixed by the limiting mechanism 2. The lifting cylinder 101 then drives the rubber-coated wheel clamping mechanism 103 to move downwards along the lifting guide rail 102 until it reaches the pressing position. Finally, the translation mechanism 105 drives the moving frame and the rubber-coated wheel clamping mechanisms 103 on both sides to move towards the other end of the rubber strip, pressing the rubber strip onto the sunroof guide rails, thus achieving automatic pressing of the rubber strip.

[0023] Please see Figure 3The rubber-coated roller clamping mechanism 103 includes a mounting plate, which is fixedly connected to the piston rod of the lifting cylinder 101. A pressure sensor 1035 is fixedly connected to the bottom of the mounting plate, and a parallel gripper cylinder 1031 is horizontally fixedly connected to the bottom of the pressure sensor 1035. Several guide rods are provided between the mounting plate and the parallel gripper cylinder 1031. A linear bearing 1036 is provided at the connection between the mounting plate and the guide rods. A pair of transverse rubber-coated rollers 1032 are symmetrically rotatably connected to the piston rod of the parallel gripper cylinder 1031. A rubber strip is fixedly connected to the side of the parallel gripper cylinder 1031. The guide block 1034 has a guide groove for the rubber strip at its bottom. The rubber strip guide block 1034 is rotatably connected to a longitudinal rubber-coating roller 1033 on the side facing the parallel gripper cylinder 1031. The longitudinal rubber-coating roller 1033 is located above the gap between a pair of transverse rubber-coating rollers 1032. The axis of the transverse rubber-coating rollers 1032 is perpendicular to the horizontal plane, and the axis of the longitudinal rubber-coating roller 1033 is parallel to the extension and retraction direction of the parallel gripper cylinder 1031. The piston chambers of the lifting cylinder 101 and the parallel gripper cylinder 1031 are both connected to pressure regulating valves 104 via pipelines. When the rubber-coating roller clamping mechanism 103 descends to the pressing position, the longitudinal rubber-coating roller 1033 presses against the pre-installed rubber strip, and the rubber strip is engaged in the rubber strip limiting groove at the bottom of the rubber strip guide block 1034, thereby limiting the lateral position of the rubber strip and preventing it from shifting during the rolling process. At this time, the parallel gripper cylinder 1031 drives a pair of transverse rubber-coating rollers 1032 to clamp both sides of the rubber strip, achieving all-round rolling of the rubber strip and improving the sealing performance of the rubber strip installation. The pressure regulating valve 104 can... The downward pressure of the lifting cylinder 101 and the holding force on both sides of the parallel gripper cylinder 1031 are adjusted to keep the pressure on the rubber strip stable during the rolling process of the longitudinal rubber-coated roller 1033 and the transverse rubber-coated roller 1032. The upper surface of the sunroof guide rail is usually curved. The rolling motion is carried out by the longitudinal rubber-coated roller 1033. The rubber-coated roller clamping mechanism 103 can rise and fall with the curvature of the sunroof guide rail. The magnitude of the downward pressure can be monitored in real time by the pressure sensor 1035.

[0024] Please see Figure 4The limiting mechanism 2 includes a pair of guide rail contour blocks 201. The pair of guide rail contour blocks 201 are symmetrically arranged on both sides of the translation mechanism 105 along the translation direction of the translation mechanism 105. Several pin hole positioning blocks 202 are fixedly connected to the side of the guide rail contour block 201 facing the translation mechanism 105. Several rotary pressing cylinders 203 are fixedly connected to the side of the guide rail contour block 201 away from the translation mechanism 105. The piston rod of the rotary pressing cylinder 203 is fixedly connected to a pressing block. A laser sensor 204 is provided on the end of the guide rail contour block 201 away from the translation mechanism 105. When fixing the sunroof guide rail, place it on the guide rail contour block 201, fix the guide rail position through the pin hole positioning block 202, then place the entire rubber strip on the guide rail, pre-install a small distance, and then drive the pressure block to press and fix the rubber strip by rotating the pressing cylinder 203. During rolling, when the rubber-coating wheel clamping mechanism 103 moves in front of the first set of rotating pressing cylinders 203, the rotating pressing cylinder 203 corresponding to the clamping mechanism 103 will open in advance, so that the pressure block is disengaged from the rubber strip. The subsequent steps are the same as above, thereby ensuring the stability of the rubber strip during pressing and avoiding the rubber strip from shifting during pressing.

[0025] Working principle: During pressing, the left and right sunroof guide rails are manually placed on top of the limiting mechanism 2. The limiting mechanism 2 limits the left and right sunroof guide rails. During installation, the sunroof guide rails are placed on the guide rail contour block 201, and the guide rail position is fixed by the pin hole positioning block 202. Then, the entire rubber strip is placed on the guide rail, with a small pre-installation distance. Then, the pressure block is driven by rotating the pressing cylinder 203 to press and fix the rubber strip. Then, the lifting cylinder 101 drives the rubber-coated wheel clamping mechanism 103 to move downward along the lifting guide rail 102. The process continues until the rubber-coating roller clamping mechanism 103 moves to the pressing position. At this point, the longitudinal rubber-coating roller 1033 presses down on the pre-installed rubber strip, and the rubber strip is engaged in the rubber strip limiting groove at the bottom of the rubber strip guide block 1034, thereby limiting the left and right positions of the rubber strip and preventing it from shifting during the rolling process. The parallel gripper cylinder 1031 drives a pair of transverse rubber-coating rollers 1032 to clamp both sides of the rubber strip, achieving all-round rolling of the rubber strip and improving the sealing of the rubber strip installation. The pressure regulating valve 104 can control the downward pressure of the lifting cylinder 101. The force and the clamping force on both sides of the parallel gripper cylinder 1031 are adjusted to ensure that the pressure of the longitudinal rubber-coating roller 1033 and the transverse rubber-coating roller 1032 on the rubber strip remains stable during the rolling process. Finally, the translation mechanism 105 drives the moving frame and the rubber-coating roller clamping mechanism 103 on both sides to move towards the other end of the rubber strip. The longitudinal rubber-coating roller 1033 and the transverse rubber-coating roller 1032 press the rubber strip onto the sunroof guide rail, realizing the automatic pressing of the rubber strip. During the pressing process, the upper surface of the sunroof guide rail is usually curved. The longitudinal rubber-coated roller 1033 rolls in real time, and the rubber-coated roller clamping mechanism 103 can rise and fall with the arc of the sunroof guide rail. The pressure sensor 1035 can monitor the downward pressure in real time. When the rubber-coated roller clamping mechanism 103 moves in front of the first set of rotating downward cylinders 203 during rolling, the rotating downward cylinder 203 corresponding to the clamping mechanism 103 will open in advance, so that the pressure block is separated from the rubber strip. The subsequent steps are the same as above, thereby ensuring the stability of the rubber strip during pressing and avoiding the rubber strip from shifting during pressing.
