Description

Technical Field

[0001] The present invention relates to the technical field of seal strip detection, and particularly relates to an automobile seal strip detection device. Background Art

[0002] Automobile seal strips are rubber or other flexible material strips applicable to parts such as automobiles, windows, roofs, hoods, and trunks. Their main function is to isolate air, moisture, and dust inside and outside the vehicle, providing a comfortable and safe driving experience. Existing automobile seal strips need to undergo many tests during the production process. For example, the patent with the authorization announcement number CN219573743U discloses a quality detection device for vehicle seal strips. Although it can stretch different parts of the seal strip simultaneously, thereby reducing the impact of inconsistent force on the seal strip on the test results, due to the different environments in which the automobile is located, the impact on the seal strip is also different. The above patent cannot test the performance of the seal strip in different environments, especially cannot detect the performance of the seal strip in an environment with sudden temperature changes. Sudden temperature changes will accelerate the thermal expansion and contraction of the automobile seal strip, and then repeated stretching can simulate the deformation that may occur during use. In view of this, the present invention provides an automobile seal strip detection device to solve the above-mentioned technical problems. Summary of the Invention

[0027] An automobile sealing strip detection device, as Figures 1-10 shown, includes a base 101. A support plate 102 is installed on the top surface of the base 101. A gantry 103 is fixedly connected to the support plate 102. A sealed box 104 is symmetrically and slidably connected inside the gantry 103. The sealed boxes 104 are driven by a linear module to move closer to or away from each other. The linear module is a prior art. A clamping assembly for clamping an automobile sealing strip is arranged in the middle of the sealed box 104. An air outlet pipe 105 and an air inlet pipe 106 are respectively fixedly connected to the upper and lower sides of the middle part of the gantry 103. Grooves matching the air outlet pipe 105 and the air inlet pipe 106 are arranged on one side of the sealed box 104 where they are close to each other. The arrangement of the grooves enables a relatively airtight space to be formed after the two sealed boxes 104 are closed. A air supply assembly is installed on the top surface of the base 101. The air supply assembly is communicated with the air inlet pipe 106. A vacuum pump 109 is installed on the top surface of the base 101. The vacuum pump 109 is connected to the air outlet pipe 105 through a pipeline; Specifically, the air supply component includes a piston cylinder 301 installed on the top surface of the base 101. The top of the piston cylinder 301 is rotatably connected to a turntable 303 in a sealed manner. An air vent is provided at the center of the turntable 303, and the air vent is connected to the intake pipe 106. A movable plug plate 302 is slidably connected to the piston cylinder 301 in a sealed manner. An elastic member 305 is provided between the bottom surface of the movable plug plate 302 and the piston cylinder 301. The elastic member 305 is specifically a spring. A buffer rubber 307 for buffering is fixedly connected to the inner top of the piston cylinder 301. The buffer rubber 307 can slow down the impact force of the movable plug plate 302. The air supply component further includes an air box 401 fixedly connected to the top surface of the base 101. Two partition plates 402 are evenly and fixedly connected inside the air box 401. The partition plates 402 divide the air box 401 into three chambers, namely a hot air chamber 4011, a normal temperature chamber 4012, and a cold air chamber 4013. A heating rod 403 and a refrigerator 404 are respectively installed in the hot air chamber 4011 and the cold air chamber 4013. Air delivery pumps 405 are installed in the hot air chamber 4011, the normal temperature chamber 4012, and the cold air chamber 4013. A shielding plate 304 is fixedly connected above the piston cylinder 301 through a connecting plate 306. Three second air vents 3041 are provided on the shielding plate 304. The three second air vents 3041 are connected to the corresponding chambers through air ducts 406. A first air vent 3031 is provided on the turntable 303. A check valve is provided in the first air vent 3031. By rotating the turntable 303, the first air vent 3031 can be communicated with the second air vent 3041; Specifically, the clamping component includes electric slide rails 201 symmetrically installed on the outer side walls of the gantry 103. A support frame 202 is installed on the electric slide rails 201. A tester 203 is installed on the support frame 202. An electric gripper 205 is provided inside the sealed box 104. The electric gripper 205 is connected to the tester 203 through a connecting rod 204. The connecting rod 204 penetrates through the sealed box 104 in a sealed manner; Furthermore, it further includes an electric push rod 504 installed on the top surface of the base 101. A connecting rod 503 is fixedly connected to the telescopic rod of the electric push rod 504. A second plug 502 and a first plug 501 are respectively fixedly connected to the upper and lower parts of the connecting rod 503. The first plug 501 and the second plug 502 are respectively slidably connected to the intake pipe 106 and the outlet pipe 105 in a sealed manner. The first plug 501 and the second plug 502 do not block the intake pipe 106 and the outlet pipe 105 simultaneously. A conical surface 5011 is provided at one end of the first plug 501 close to the intake pipe 106. The conical surface 5011 can slow down the impact of the air flow and prevent the first plug 501 from being impacted; It can be seen from this that during use, first use the electric grippers 205 on the left and right sides to clamp the automotive sealing strip, then start the linear module to make the two sealing boxes 104 approach each other, so that the two sealing boxes 104 wrap the automotive sealing strip in a relatively enclosed space. Then start the vacuum pump 109, and the vacuum pump 109 evacuates the air in the sealing box 104, making the inside of the sealing box 104 in a vacuum state, and then the temperature inside the sealing box 104 decreases. At this time, the temperature is the set initial value temperature. Then start the electric slide rail 201 to make the two support frames 202 move away from each other, so that the two electric grippers 205 move away from each other, and then the stretching of the automotive sealing strip can be realized. The tester 203 can test relevant data, and then the stretching test of the automotive sealing strip can be carried out. After the tester 203 finishes reading the data, keep the position of the electric gripper 205 unchanged to make the automotive sealing strip in a stretched state, rotate the turntable 303, so that the first air vent 3031 communicates with the corresponding second air vent 3041, and then start the corresponding air delivery pump 405. For example, if it is necessary to detect the change in the tensile force of the automotive sealing strip at high temperature, the air delivery pump 405 introduces external air into the hot air chamber 4011. The heating rod 403 in the hot air chamber 4011 heats the air to form hot air. The hot air enters the piston cylinder 301 through the air duct 406, the second air vent 3041 and the first air vent 3031, so that the movable plug plate 302 slides downward, squeezing the elastic member 305, so that the elastic member 305 is compressed and stores elastic potential energy. Then start the electric push rod 504, and the telescopic rod of the electric push rod 504 extends, driving the connecting rod 503 to move upward, so that the first plug head 501 moves upward, and the first plug head 501 no longer blocks the air inlet pipe 106, so that the two spaces inside the sealing box 104 and the piston cylinder 301 are communicated. At the same time, due to the upward movement of the connecting rod 503, the second plug head 502 is driven to move upward, so that the second plug head 502 blocks the air outlet pipe 105. At the same time, since the inside of the sealing box 104 is in a vacuum negative pressure state and the piston cylinder 301 is filled with gas, a pressure difference is generated. At the same time, the elastic member 305 returns to its original position and releases elastic potential energy, pushing the movable plug plate 302 upward, so that the gas in the piston cylinder 301 can be instantly pushed out, so that the temperature inside the sealing box 104 changes suddenly. In this way, while completing the sudden temperature change, because the gas is instantly pushed out, it also avoids the situation that the continuous injection of gas causes uneven temperature distribution and affects the detection results. At the same time, the buffer rubber 307 buffers the movable plug plate 302, and the conical surface 5011 disperses the impact of the air flow on the first plug head 501. At this time, by observing the numerical change on the tester 203, the anti-softening ability of the automotive sealing strip under sudden temperature change can be detected. The principle of cold air is the same, so it will not be elaborated here. In this way, the performance of the automotive sealing strip in different use environments can be comprehensively understood to ensure that it can work properly under various climatic conditions.The reliability and practicality of the test results are improved, meeting diverse test requirements.

[0028] Furthermore, it also includes a spraying component. The spraying component includes a water storage pipe 602 rotatably connected to the upper part inside the sealed box 104. A nozzle 603 is installed on the water storage pipe 602. A water tank 601 is installed on the top surface of the base 101. The water tank 601 is connected to the water storage pipe 602 through a water pump and a pipeline. The spraying component also includes a gear 604 rotatably connected to the side wall of the sealed box 104. The gear 604 is fixedly connected to one end of the water storage pipe 602. A connecting frame 606 is also slidably connected to the side wall of the sealed box 104. A rack 605 meshing with the gear 604 is fixedly connected to the connecting frame 606. The connecting frame 606 is in an "L" shape. A limiting hole 2041 is provided on the connecting rod 204. A limiting screw 607 matching with the limiting hole 2041 is threadedly connected to the connecting rod 204. From this, it can be known that when the automotive sealing strip needs to be tested for fatigue resistance, the electric slide rail 201 can be started, so that the two support frames 202 reciprocally move away from or close to each other, and then the two electric grippers 205 reciprocally move away from or close to each other, and thus the fatigue resistance test of the automotive sealing strip can be realized. And when the support frame 202 moves, the limiting screw 607 is rotated so that the limiting screw 607 is inserted into the limiting hole 2041. Then, when the connecting rod 204 moves, it will drive the connecting frame 606 to slide on the side wall of the sealed box 104, and then drive the rack 605 to slide. The sliding of the rack 605 drives the gear 604 to rotate through meshing transmission. The rotation of the gear 604 drives the water storage pipe 602 to rotate, and then the nozzle 603 rotates. The water pump is started, and then the water pump pumps out the water in the water tank 601 and conveys it to the water storage pipe 602 through the pipeline and sprays it out from the nozzle 603. Thus, the test under a high-humidity environment in rainy days can be simulated. And because the nozzle 603 rotates, the nozzle 603 does not spray statically, and thus the changes in the external dynamic environment such as rainy days that the automotive sealing strip needs to cope with in actual use can be simulated, increasing the comprehensiveness and accuracy of the test.
