Description

Technical Field

[0001] This utility model relates to the field of sealing strip processing technology, specifically a sealing strip positioning device. Background Technology

[0002] With the development of technology, rubber products are widely used in all aspects of people's lives, such as various rubber seals, tires, windshield wipers, and automotive sealing strips. Automotive sealing strips are calendered and vulcanized in a mold, and the ends of the formed automotive sealing strips need to be trimmed. The announcement number is: CN. 217292540U, specifically, describes an automotive sealing strip positioning device, comprising a worktable, a loading plate located at the middle of the rear end of the worktable, a lateral displacement module located on the upper front side of the loading plate, a vertical displacement module mounted on the slide of the lateral displacement module, a clamping cylinder located on the lower front side of the carrying plate, a limit plate located at the rear end of the worktable, and a movable clamping plate mounted at the end of the worktable via a positioning groove. The lateral displacement module, vertical displacement module, and clamping cylinder enable convenient and efficient positioning of the sealing strip, thereby improving the positioning efficiency of the sealing strip. The scale markings and pointers allow for precise adjustment of the distance between the limit plate and the movable clamping plate, resulting in good positioning performance of the sealing strip. The limit post and adapter plate ensure high stability of the movable clamping plate's movement and positioning, further enhancing the positioning performance of the sealing strip.

[0003] The above solution has the following shortcomings in actual use: the clamping cylinder is adjusted by the horizontal displacement module and the vertical displacement module to pull the sealing strip and make the sealing strip complete the positioning. However, due to the elasticity of the sealing strip itself, it is easy to pull the sealing strip too much in this process, causing the sealing strip to rebound after cutting, resulting in inaccurate cutting length of the sealing strip. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sealing strip positioning device, which has the advantage of uniformly positioning and cutting the length of the sealing strip, thus avoiding the problem of inaccurate cutting of the sealing strip length.

[0020] 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.

[0021] Reference Figures 1-4 A sealing strip positioning device includes a worktable 1, a first positioning plate 101 fixedly connected to the top of the worktable 1, a second positioning plate 102 slidably connected to the top of the worktable 1, and a positioning assembly 2 installed on the top of the worktable 1 for positioning the sealing strip. The device also includes:

[0022] The positioning component 2 includes a connecting frame 201, which is fixedly installed on the top of the workbench 1. A first telescopic cylinder 202 is fixedly connected to the top of the connecting frame 201. A connecting box 203 is fixedly connected to the output end of the first telescopic cylinder 202. A mounting frame 204 is slidably connected to the inner wall of the connecting box 203. A roller 205 is rotatably connected to the inner wall of the mounting frame 204. A pressure plate 206 is fixedly connected to the bottom of one side of the connecting box 203, and the bottom of the pressure plate 206 and the roller 205 are flush.

[0023] The side walls of the pressure plate 206 and the mounting bracket 204 are both fixedly connected to the connecting plate 207, and the top of the connecting plate 207 is fixedly connected to the second telescopic cylinder 208.

[0024] The output end of the second telescopic cylinder 208 is fixedly connected to a cutter 209, and the cutter 209 can extend to the bottom of the pressure plate 206 and the roller 205;

[0025] It should be noted that: the sealing strip is placed between the first positioning plate 101 and the second positioning plate 102, and then the second positioning plate 102 is slid to clamp it between the first positioning plate 101 and the second positioning plate 102. The first telescopic cylinder 202 at the top of the drive connecting frame 201 causes the connecting box 203 to slide down until the pressure plate 206 and the roller 205 are both pressed against the top of the sealing strip, with the roller 205 tightly against the pressure plate 206. Then, the mounting bracket 204 slides within the connecting box 203, at which point the mounting bracket 204 drives the roller 205. Sliding on top of the sealing strip, the roller 205 can flatten the sealing strip in sequence, preventing it from bending due to its own elasticity. After sliding the roller 205 to the cutting position, the second positioning plate 102 can be moved away from the sealing strip to avoid affecting the subsequent cutting of the sealing strip by the cutter 209. At the same time, the second telescopic cylinder 208 on the side wall of the pressure plate 206 and the roller 205 is driven to drive the cutter 209 to slide down and cut the sealing strip. At this time, the cutting of the sealing strip between the pressure plate 206 and the roller 205 can be completed. In summary, the cutting length can be adjusted to facilitate the processing of sealing strips of various specifications.

[0026] Reference Figures 1-4 A side plate is fixedly connected to the side wall of the workbench 1, and a third telescopic cylinder 3 is fixedly connected to the side wall of the side plate. The output end of the third telescopic cylinder 3 is fixedly connected to the second positioning plate 102.

[0027] The top of the workbench 1 is provided with a slide groove 301, and the second positioning plate 102 is slidably connected to the slide groove 301;

[0028] It should be noted that the third telescopic cylinder 3 of the drive side plate side wall drives the second positioning plate 102 to move towards the first positioning plate 101, thereby clamping the sealing strip between the first positioning plate 101 and the second positioning plate 102, preventing the sealing strip from bending and deforming to both sides, which would lead to cutting failure. In addition, the second positioning plate 102 and the slide groove 301 facilitate the linear movement of the second positioning plate 102, ensuring accurate positioning.

[0029] Reference Figures 1-4 A servo motor 4 is fixedly connected to the side wall of the connecting box 203, and a threaded post 401 is fixedly connected to the output end of the servo motor 4.

[0030] The threaded post 401 is threadedly connected to the mounting bracket 204;

[0031] It should be noted that: the servo motor 4 drives the threaded post 401 to rotate. The threaded connection between the threaded post 401 and the mounting bracket 204 allows the mounting bracket 204 to drive the roller 205 to slide on the top of the sealing strip, thereby pressing the sealing strip and facilitating subsequent cutting.

[0032] Operating method: Place the sealing strip between the first positioning plate 101 and the second positioning plate 102, drive the third telescopic cylinder 3 on the side wall of the side plate, so that it drives the second positioning plate 102 to move towards the first positioning plate 101, thereby clamping the sealing strip between the first positioning plate 101 and the second positioning plate 102 to prevent the sealing strip from bending and deforming to both sides, which would lead to cutting failure. The first telescopic cylinder 202 at the top of the connecting frame 201 can be driven to drive the connecting box 203 to slide down until the pressure plate 206 and the roller 205 are pressed against the top of the sealing strip, wherein the roller 205 is in close contact with the pressure plate 206.

[0033] The servo motor 4 is driven to rotate the threaded post 401. The threaded connection between the threaded post 401 and the mounting bracket 204 allows the mounting bracket 204 to drive the roller 205 to slide on top of the sealing strip. The roller 205 can flatten the sealing strip in sequence, preventing it from bending due to its own elasticity. After the roller 205 is slid to the cutting position, the second positioning plate 102 can be moved away from the sealing strip to avoid affecting the subsequent cutting of the sealing strip by the cutter 209. At the same time, the second telescopic cylinder 208 on the side wall of the pressure plate 206 and the roller 205 is driven to drive the cutter 209 to slide down and cut the sealing strip. At this time, the cutting of the sealing strip between the pressure plate 206 and the roller 205 can be completed. In summary, the cutting length can be adjusted to facilitate the processing of sealing strips of various specifications.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
