Description

Technical Field

[0001] The utility model belongs to the technical field of automobile assembly tools, and particularly relates to a rolling tool for automobile trunk sealing strips. Background Art

[0002] Automotive sealing strips fill the gaps and crevices between vehicle body components, providing shock absorption, waterproofing, dustproofing, sound insulation, and decorative functions, enhancing driving comfort and protecting the vehicle body. During vehicle production, sealing strips are primarily installed manually. This method cannot guarantee proper installation and is highly likely to result in leaks during rain tests, increasing repair time. Furthermore, manual installation takes a long time, increasing production timelines and costs.

[0003] Patent application number CN201910643371.4 discloses a rolling tool for automobile trunk sealing strips, comprising: a transmission mechanism that provides a guiding force for the sealing strip during installation; a pressing mechanism that presses against the trunk sealing strip to ensure it fits snugly against the trunk; and a housing that supports the transmission mechanism and the pressing mechanism. The housing also includes a rotating mechanism. In this technical solution, the spacing between the active and passive rollers is fixed, while the specifications of trunk sealing strips vary between different vehicle models. Therefore, during production, different rolling tools need to be replaced based on the specific sealing strip, resulting in high costs.

[0004] In view of this, the inventors conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

[0005] The purpose of the utility model is to provide a rolling tool for a car trunk sealing strip, which can change the distance between two rollers to adapt to sealing strips of different specifications and reduce production costs.

[0006] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0007] A rolling tool for a car trunk sealing strip comprises a first rolling mechanism for rolling both sides of the sealing strip, a second rolling mechanism for rolling the top of the sealing strip, and an installation shell, wherein the first rolling mechanism comprises two parallel rollers and a rolling sleeve detachably connected to the rollers, and the rollers are rotatably connected to the shell; a plurality of limiting grooves extending along the axial direction of the rollers are formed on the rollers, a limiting strip cooperating with the limiting grooves is formed on the inner wall of the rolling sleeve, a threaded hole is formed at the end of the roller, a groove is formed at the top of the rolling sleeve, and a bolt threadedly cooperating with the threaded hole is provided in the groove.

[0008] Furthermore, the first rolling mechanism also includes a first gear and a second gear, each fixedly mounted on the roller. The transmission ratio between the first gear and the second gear is 1:1. By using the two gears to drive the two rollers to rotate simultaneously in opposite directions, the first rolling mechanism can more smoothly roll both sides of the sealing strip.

[0009] Furthermore, the housing is also provided with a connecting sleeve for connecting the entire rolling tool to the robotic arm. The entire rolling tool can be connected to the robotic arm through the connecting sleeve without manual operation.

[0010] Furthermore, the first rolling mechanism further includes a connecting key bar connected to the tail of one of the rollers, the other end of the connecting key bar being connected to the power mechanism of the robotic arm; the connecting key bar being located within the connecting sleeve, and the roller can be connected to the power mechanism via the connecting key bar.

[0011] Furthermore, the second rolling mechanism includes a rolling wheel, support assemblies disposed at both ends of the rolling wheel, and a rotating shaft connected to the ends of the two support assemblies; the rolling wheel is rotatably connected to the rotating shaft. The second rolling mechanism can be used to roll the top of the sealing strip, ensuring a tighter installation of the sealing strip.

[0012] Furthermore, the support assembly includes a mounting sleeve fixedly connected to the housing, a support sleeve slidably connected within the mounting sleeve, and a spring connected between the mounting sleeve and the support sleeve; one end of the spring is fixedly connected to the inner bottom wall of the mounting sleeve, and the other end is fixedly connected to the inner top wall of the support sleeve. The spring allows the rolling wheel to adapt to sealing strips of different heights and allows the rolling wheel to pass more smoothly around corners during rolling.

[0013] After adopting the above structure, the utility model involves a rolling tool for a car trunk sealing strip. Compared with the existing technology, this case connects the rolling sleeve to the roller in a detachable manner. If sealing strips of different specifications are encountered, it is only necessary to replace the rolling sleeves of different thicknesses. It can adapt to sealing strips of different specifications without the need to equip multiple rolling tools, thereby greatly reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts in the drawings or in the specification are numbered the same. Implementations not shown or described in the drawings are forms known to those skilled in the art.

[0024] like Figures 1 to 7As shown, the utility model relates to a rolling tool for a car trunk sealing strip, comprising a first rolling mechanism 1 for rolling both sides of the sealing strip, a second rolling mechanism 2 for rolling the top of the sealing strip, and a mounting shell 3. A connecting sleeve 31 is provided on the mounting shell 3, which is connected to the robot arm through the connecting sleeve 31. Specifically, a threaded connection or a snap connection that is convenient for disassembly and assembly can be adopted; the first rolling mechanism 1 and the second rolling mechanism 2 are driven by the robot arm to roll both sides and the top of the sealing strip at the same time. In addition, a 3D camera is provided on the robot arm, which uses the 3D camera to measure the contour of the trunk. Scanning is performed, the trajectory is planned, and the rolling tool is driven by the robotic arm to perform rolling; the first rolling mechanism 1 includes two parallel rollers 11 and a rolling sleeve 12 detachably connected to the roller 11, and the roller 11 is rotatably connected to the shell; a plurality of limiting grooves 111 extending along the axial direction of the roller 11 are formed on the roller 11, and a limiting strip 121 cooperating with the limiting groove 111 is formed on the inner wall of the rolling sleeve 12, a threaded hole 112 is formed at the end of the roller 11, and a groove 122 is formed on the top of the rolling sleeve 12, and the groove 122 is provided with a bolt 13 threadedly matched with the threaded hole 112. When it is necessary to install sealing strips for different models, the width and height of the sealing strips are different. At this time, there is no need to replace the entire rolling tool. Only the rolling sleeves 12 of different thicknesses need to be replaced. When installing the rolling sleeve 12, align the limiting strip 121 of the rolling sleeve 12 with the limiting slide groove 111 of the roller 11 and put it down. The cooperation between the limiting slide groove 111 and the limiting strip 121 can prevent the rolling sleeve 12 and the roller 11 from rotating relative to each other. Then, the roller 11 and the rolling sleeve 12 are fixed by bolts 13 to avoid axial movement of the roller 11 and the rolling sleeve 12. A groove 122 is formed at the end of the rolling sleeve 12 to hide the bolt 13 inside to prevent the bolt 13 from damaging the sealing strip.

[0025] Preferably, the first rolling mechanism 1 also includes a first gear 14 and a second gear 15 respectively fixedly mounted on the roller 11; the transmission ratio of the first gear 14 to the second gear 15 is 1:1. By using two gears to drive the two rollers 11 to rotate simultaneously in opposite directions at the same speed, the first rolling mechanism 1 can be made smoother when rolling both sides of the sealing strip. Specifically, the first rolling mechanism 1 also includes a connecting key bar 16 connected to the tail of one of the rollers 11. The connecting key bar 16 is a spline, and the other end of the connecting key bar 16 is connected to the power mechanism of the robotic arm; the connecting key bar 16 is located in the connecting sleeve 31, and the roller 11 can be connected to the power mechanism through the connecting key bar 16.

[0026] Preferably, the second rolling mechanism 2 includes a rolling wheel 21, support assemblies 22 provided at both ends of the rolling wheel 21, and a rotating shaft 23 connected to the ends of the two support assemblies 22; the rolling wheel 21 is rotatably connected to the rotating shaft 23. The second rolling mechanism 2 can be used to roll the top of the sealing strip, making the installation of the sealing strip tighter. Specifically, the support assembly 22 includes a mounting sleeve 221 fixedly connected to the housing, a support sleeve 222 slidably connected within the mounting sleeve 221, and a spring 223 connected between the mounting sleeve 221 and the support sleeve 222; one end of the spring 223 is fixedly connected to the inner bottom wall of the mounting sleeve 221, and the other end is fixedly connected to the inner top wall of the support sleeve 222. The spring 223 allows the rolling wheel 21 to adapt to sealing strips of different heights, and during rolling, the rolling wheel 21 can pass through corners more smoothly.

[0027] The above describes in detail the automobile trunk sealing strip rolling tool provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the claims of the present invention.
