Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically to a performance testing device for automotive sealing strips. Background Technology
[0002] As a critical component of the vehicle body, automotive weatherstripping is primarily installed in areas such as doors, windows, and trunks, fulfilling the core function of isolating the vehicle from the internal and external environments. Its performance directly affects the vehicle's sealing performance, sound insulation, waterproofing, dustproofing, and passenger cabin comfort. Air tightness is one of the most critical indicators of weatherstripping quality. Implementing rigorous and efficient air tightness testing during the weatherstripping production process is an indispensable and crucial step in ensuring product quality, meeting the stringent standards of OEMs, and guaranteeing the end-user experience.
[0003] Currently, on automotive sealing strip production lines, specialized testing equipment is commonly used to test airtightness. Existing testing procedures require operators to manually move the sealing strip to be tested and precisely place it onto the tooling or fixture of the testing equipment; then, the equipment is started for testing. During the testing process, operators typically need to wait beside the equipment for the test to complete. The test results are usually displayed via indicator lights, instrument readings, or simple screen prompts; operators must visually observe and manually judge the results; finally, based on the judgment, the sealing strip is manually removed and classified into the qualified or unqualified product area. The time spent by operators in placing, waiting for results, and removing the workpieces, coupled with the equipment being idle while waiting for manual operation, results in low actual equipment utilization, limiting the maximum capacity of the testing station and hindering continuous testing.
[0004] Based on this, a performance testing device for automotive sealing strips is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] In one embodiment, such as Figures 1-7 As shown, an automotive sealing strip performance testing device includes a switching seat 11 and a mounting seat 14. The two ends of the switching seat 11 are rotatably mounted in the rotating holes inside the mounting box 13. A plurality of mounting seats 14 are arrayed on the switching seat 11. Limiting plates are fixed at both ends of the mounting seats 14. A vent groove is provided in the middle of the mounting seat 14. A plurality of exhaust holes are provided at the upper end of the mounting seat 14. Clamping mechanisms for clamping and fixing the sealing strip body 32 are provided on both sides of the mounting seat 14. The sealing strip body 32 is installed on one side of the limiting plate. The mounting box 13 is provided with a testing mechanism for testing the sealing strip body 32. The clamping mechanism facilitates the clamping and fixing of the sealing strip body 32, and the testing mechanism facilitates automatic testing of the sealing strip body 32.
[0027] One end of the switching seat 11 is fixedly connected to the output end of the motor 12. The motor 12 is fixedly mounted on one side of the mounting box 13. The motor 12 is electrically connected to the control component 30. The control component 30 is fixedly mounted on one side of the mounting box 13. In use, when continuous feeding detection of the sealing strip body 32 is required, the motor 12 is controlled to rotate by the control component 30. The motor 12 rotates 90 degrees each time, which facilitates continuous feeding detection. It is worth noting that the control component 30 in this application uses existing components, and its control method adopts known technology.
[0028] The clamping mechanism includes a clamping plate 17. Clamping plates 17 are fitted on both sides of the mounting base 14. A plurality of guide slide rods are arrayed on one side of each clamping plate 17. A first fixing plate is slidably mounted on each guide slide rod. Each first fixing plate is fixedly mounted on the switching base 11. A return spring 20 is provided between one end of each guide slide rod and one side of the first fixing plate. First connecting rods 18 are hinged to both ends of the clamping plate 17. The other end of each first connecting rod 18 on the same side is hinged to both ends of a first hinge rod 19. One side of the first hinge rod 19 is fixed. A top rod is provided, on which a second fixing plate is slidably mounted. The second fixing plate is fixedly mounted on the switching seat 11. Inside the mounting box 13, guide components are provided at positions corresponding to both ends of the switching seat 11. Each guide component consists of several fixed arc-shaped plates 23 and sliding arc-shaped plates 24, which combine to form a guide ring. The fixed arc-shaped plates 23 are all fixedly mounted inside the mounting box 13, and the sliding arc-shaped plates 24 are fixedly mounted at the output end of the first electric cylinder 25. Several first electric cylinders 25 are also fixedly mounted... Inside the mounting box 13, the first electric cylinders 25 are all electrically connected to the control component 30. Each mounting base 14 has a fixed support rod 15 at its upper end. In use, when the sealing strip body 32 needs to be fed, the mounting base 14 rotates to the upper end of the switching base 11, and the output end of the corresponding first electric cylinder 25 drives the sliding arc plate 24 to move, causing the sliding arc plate 24 to separate from the top rod. Under the action of the return spring 20, the clamping plate 17 moves away from the mounting base 14, and then the sealing strip body 32 is installed on the mounting base 14, with the support rod 15... 5 is in close contact with the inner side of the sealing strip body 32, thereby supporting it. Both ends of the sealing strip body 32 are in close contact with the limiting plates at both ends of the mounting base 14. Then, the operator controls the output end of the first electric cylinder 25 through the control component 30 to drive the sliding arc plate 24 back to the initial position. The sliding arc plate 24 pushes the top rod to move, and the top rod drives the first hinge rod 19 to slide. The first hinge rod 19 drives the clamping plate 17 to move through the first connecting rod 18, so that the clamping plate 17 clamps and fixes the sealing strip body 32. Then, the switching base 11 drives the sealing strip body 32 to rotate.
[0029] Both ends of the clamping plate 17 are fixedly provided with sealing frames 21. One side of the limiting plate is fixedly provided with a support tube 16 corresponding to one end of the connecting tube 22. In use, when installing the sealing strip body 32, both ends of the sealing strip body 32 are respectively inserted into the two support tubes 16. When the clamping plate 17 clamps the sealing strip body 32, the clamping plate 17 drives the sealing frame 21 to move, so that the sealing frame 21 and the support tube 16 cooperate to seal and clamp the sealing strip body 32.
[0030] The detection mechanism includes a sealing detection component 29, which is fixedly mounted on the upper end of the mounting box 13. The sealing detection component 29 is electrically connected to the control component 30. Both the gas supply end and the receiving end of the sealing detection component 29 are connected to a connecting pipe, and the other end of the connecting pipe is connected to a flexible hose. One end of the flexible hose is connected to a socket joint 26, and one end of the socket joint 26 is inserted into one end of the connecting pipe 22. The inner side of the socket joint 26 is provided with several sealing rings. The mounting box 13 is provided with a plugging assembly for driving the socket joint 26 to be inserted into and separated from the connecting pipe 22.
[0031] The insertion assembly includes a sliding rod. Each of the socket joints 26 is fixedly provided with a sliding rod, which is slidably mounted on a fixed rod. The fixed rod is fixed inside the mounting box 13. Each sliding rod is hinged with a second connecting rod 27, the other end of which is hinged to a second hinge rod. The second hinge rod is fixed at the output end of a second electric cylinder 28, which is fixed in a mounting hole at the upper end of the mounting box 13. The second electric cylinder 28 is electrically connected to the control component 30. The second hinge rod is symmetrically provided with limit rods, which slidably mount in the sliding holes at the upper end of the mounting box 13. In use, when the switching seat 11 rotates the sealing strip body 32 between the two socket joints 26, the control component 30 controls the second electric cylinder 28 to start. The output end of the second electric cylinder 28 drives the second hinge rod to slide. The second hinge rod, through the second connecting rod 27, drives the socket joint 26 to slide, allowing the socket joint 26 to insert and engage with the connecting pipe 22. The gas supply end of the switching seat 11 delivers a fixed amount of gas into the sealing strip body 32 through the connecting pipe 22. Then, the receiving end of the sealing detection component 29 monitors the pressure change within a specified time. If there is a leak in the sealing strip body 32, the internal gas pressure will drop. The pressure drop data is captured by the pressure sensor inside the sealing detection component 29. After the detection is completed, the sleeve 26 separates from the connecting pipe 22, and then the switching seat 11 rotates again. When the product is qualified, the sealing strip body 32 rotates to below the switching seat 11, and the corresponding first electric cylinder 25 drives the sliding arc plate 24 to move, so that the clamping plate 17 releases the fixation of the sealing strip body 32, and then the sealing strip body 32 falls off. If the product is unqualified, after the sealing strip body 32 rotates to below the switching seat 11, the corresponding first electric cylinder 25 does not work. When the switching seat 11 rotates 90 degrees again, the output end of the corresponding first electric cylinder 25 drives the sliding arc plate 24 to move, so that the sealing strip body 32 falls off.
[0032] The bottom of the installation box 13 is equipped with a collection box 31. In use, the two collection boxes 31 are used to hold qualified products and unqualified products respectively.
[0033] The above embodiment discloses an automotive sealing strip performance testing device. When continuous feeding testing of the sealing strip body 32 is required, the control component 30 controls the motor 12 to rotate, with the motor 12 rotating 90 degrees each time. This causes the mounting base 14 to rotate to the upper end of the switching base 11, and the output end of the corresponding first electric cylinder 25 drives the sliding arc plate 24 to move, causing the sliding arc plate 24 to separate from the push rod. Under the action of the return spring 20, the clamping plate 17 moves away from the mounting base 14. Then, the sealing strip body 32 is installed on the mounting base 14, with both ends of the sealing strip body 32 respectively inserted into two support tubes 16, and the support rod 15 and the sealing strip body... The inner side of the sealing strip body 32 is tightly attached to support it, and both ends of the sealing strip body 32 are tightly attached to the limiting plates at both ends of the mounting base 14. Then, the operator controls the output end of the first electric cylinder 25 through the control component 30 to drive the sliding arc plate 24 back to the initial position. The sliding arc plate 24 pushes the top rod to move, and the top rod drives the first hinge rod 19 to slide. The first hinge rod 19 drives the clamping plate 17 to move through the first connecting rod 18, so that the clamping plate 17 clamps and fixes the sealing strip body 32. At the same time, the clamping plate 17 drives the sealing frame 21 to move, so that the sealing frame 21 cooperates with the support tube 16 to seal and clamp the sealing strip body 32. Then, the switching seat 11 drives the sealing strip body 32 to rotate.
[0034] After the switching seat 11 rotates the sealing strip body 32 between the two sleeve joints 26, the control component 30 controls the second electric cylinder 28 to start. The output end of the second electric cylinder 28 drives the second hinge rod to slide. The second hinge rod drives the sleeve joint 26 to slide through the second connecting rod 27, so that the sleeve joint 26 is inserted and engaged with the connecting pipe 22. Then, the gas supply end of the switching seat 11 delivers a certain amount of gas into the sealing strip body 32 through the connecting pipe 22. Subsequently, the receiving end of the sealing detection component 29 monitors the pressure change within a specified time. If there is a leak in the sealing strip body 32, the internal gas pressure will drop. The pressure drop data is captured by the pressure sensor inside the sealing detection component 29. After the detection is completed, the sleeve joint... The connector 26 separates from the connecting pipe 22, and then the switching seat 11 rotates again. When the product is found to be qualified, the sealing strip body 32 rotates to the bottom of the switching seat 11, and the corresponding first electric cylinder 25 drives the sliding arc plate 24 to move, so that the clamping plate 17 releases the fixing of the sealing strip body 32, and then the sealing strip body 32 falls off. If the product is found to be unqualified, the sealing strip body 32 rotates to the bottom of the switching seat 11, and the corresponding first electric cylinder 25 does not work. When the switching seat 11 rotates 90 degrees again, the output end of the corresponding first electric cylinder 25 drives the sliding arc plate 24 to move, so that the sealing strip body 32 falls into the corresponding collection box 31.
[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
