[0037] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:
[0038] Figure 1 This is a top view schematic diagram of the inspection fixture for automotive sealing strips according to an embodiment of the present invention. Figure 2 As described in the embodiments of this utility model Figure 1 A magnified view of a portion of the image. Figure 3 This is a three-dimensional schematic diagram of the fixing base in an embodiment of the present utility model. Figure 4 As described in the embodiments of this utility model Figure 3Enlarged view of point A in the image.
[0039] like Figures 1 to 4 As shown, the detection fixture for automotive sealing strips in this embodiment includes: a fixing base 1, a limiting plate 2, a sensor 3, and a controller 4.
[0040] The mounting base 1 is elongated, and its length is greater than the length of the sealing strip 100 being tested. The mounting base 1 is fixed to the surface of the workbench.
[0041] The mounting base 1 has a contoured top surface 11 and an inclined side wall. The contoured top surface 11 of the mounting base 1 is arc-shaped, and the cross-section of the contoured top surface 11 is adapted to the cross-section of the sealing strip 100. The inclined side wall is located on one side (front side) of the contoured top surface 11.
[0042] The limiting plate 2 is set on the inclined side wall of the fixed base 1. The top of the limiting plate 2 protrudes from the inclined side wall of the fixed base 1 and is spaced a certain distance from the contoured top surface 11 of the fixed base 1.
[0043] Controller 4 is mounted on the workbench surface.
[0044] The sensor 3 has a slot 31 at its top.
[0045] Multiple sensors 3 are provided, and the multiple sensors 3 are arranged at intervals on the limiting plate 2. They are electrically connected to the controller 4, and the positions of the multiple sensors 3 correspond to the positions of the multiple buckles 110 on the sealing strip 100.
[0046] In this embodiment of the detection fixture, the operator places the sealing strip (product) with buckles on the fixed base and inserts the cross-section of the sealing strip into the contoured top surface of the fixed base. At this time, the buckles on the sealing strip will enter the slots of the sensor respectively.
[0047] Press the start button, and the sensor will detect the clips at each position of the sealing strip. When the sensor detects a clip, it will send a detection signal to the controller. If all sensors detect a clip, the controller will display that the sealing strip (product) is qualified. If any sensor fails to detect a clip, it means that a clip is not installed at a certain position, and the controller will display that the sealing strip (product) is unqualified.
[0048] As can be seen from the above, the testing fixture for automotive sealing strips in this embodiment comprises a fixed base, a limiting plate, sensors, and a controller. The fixed base has a contoured top surface and an inclined side wall. The limiting plate is located on the inclined side wall. The sensors have slots, and multiple sensors are mounted on the limiting plate, each electrically connected to the controller. Each sensor corresponds to a specific snap fastener on the sealing strip. In this embodiment, the operator inserts the cut end of the sealing strip (product) onto the contoured top surface of the fixed base, causing the snap fasteners on the sealing strip to enter the slots of the sensors. The sensors detect the snap fasteners at various positions on the sealing strip and send detection signals to the controller. If all sensors detect snap fasteners, the controller displays that the sealing strip is a qualified product. If any sensor fails to detect a snap fastener, it indicates that a snap fastener is not installed, and the controller displays that the sealing strip is a defective product. The operator then checks the sealing strip, adds any missing snap fasteners, and retests until the test results are qualified, thus preventing defective products from leaving the product and ensuring smooth subsequent installation.
[0049] Optionally, in this embodiment, the detection fixture for automotive sealing strips includes a controller 4 equipped with a red alarm light 41 and a green indicator light 42.
[0050] When all sensors 3 detect the latch 110, the green indicator light 42 of the controller 4 will light up, indicating that the product (sealing strip) is qualified; when a sensor 3 fails to detect the latch 110, the red alarm light 41 of the controller 4 will light up, indicating that the product is unqualified.
[0051] Furthermore, in this embodiment, the red alarm light 41 of the controller 4 for the automotive sealing strip testing fixture is an audible and visual alarm light. When it is lit (indicating product defect), it also emits an audible alarm to more conspicuously remind the operator.
[0052] Furthermore, the detection fixture for automotive sealing strips in this embodiment also includes a red indicator light 5.
[0053] Multiple red indicator lights 5 are provided and are set on the workbench, located on one side of the fixed base 1, and the positions of the multiple red indicator lights 5 correspond to the positions of the multiple sensors 3 respectively.
[0054] Red indicator lights 5 are electrically connected to controller 4.
[0055] In this embodiment, when all sensors detect the latch, the green indicator light on the controller illuminates, indicating that the product is qualified. When a sensor fails to detect the latch, the red alarm light on the controller illuminates, and the red indicator light corresponding to the sensor that failed to detect the latch illuminates, indicating that the sealing strip is missing a latch at that position, making it convenient for the operator to reinstall the latch.
[0056] Optionally, in this embodiment, the inspection fixture for automotive sealing strips has a center line 12 and upper and lower tolerance lines 13 at one end of the contoured top surface 11, with the upper and lower tolerance lines 13 located to the left and right of the center line 12, respectively.
[0057] When the sealing strip is placed, the corresponding end of the sealing strip 100 is placed in the area between the upper and lower tolerance lines 13 of the fixed base 1, and is basically aligned with the center line 12, so that the buckle 110 on the sealing strip 100 is basically aligned with the slot 31 of the sensor 3, and the buckle 110 can be smoothly inserted into the slot 31 of the sensor 3.
[0058] Furthermore, in this embodiment, the inspection fixture for automotive sealing strips has a center line 12 and upper and lower tolerance lines 13 on both the left and right ends of the contoured top surface 11.
[0059] When placing the sealing strip, either end of the sealing strip can be placed within the area between the upper and lower tolerance lines of the corresponding end, allowing the buckle to be quickly inserted into the sensor's slot, making it more convenient to use.
[0060] Optionally, in this embodiment, the detection fixture for automotive sealing strips has a notch 21 on the top of the limiting plate 2, and the sensor 3 is engaged in the notch 21 of the limiting plate 2.
[0061] Optionally, in this embodiment, the testing fixture for automotive sealing strips has a threaded hole 14 on its inclined side wall.
[0062] The limiting plate 2 is provided with a mounting through hole 22. The fixing bolt passes through the mounting through hole 22 of the limiting plate 2 and engages with the threaded hole 14 of the fixing seat 1. When the fixing bolt is tightened, the limiting plate is fixed on the fixing seat.
[0063] Furthermore, the mounting through hole 22 of the limiting plate 2 is elongated, which allows the limiting plate 2 to be fixedly fixed on the fixing base 1 in an adjustable position, making it convenient to adjust the position of the limiting plate 2.
[0064] The testing fixture of this utility model has the following usage procedure:
[0065] 1. The operator places the product (sealing strip) with the snap-fit inserted into the fixed base on the contoured top surface. At this time, the snap-fit on the product will naturally enter the sensor's slot.
[0066] 2. Press the start button on the controller, and the sensor will begin detection.
[0067] 3. Controller output test results: If the green indicator light on the controller is on, the product is qualified; if the red alarm light on the controller is on, the product is unqualified. At this time, the red indicator light at the corresponding missing buckle position will also light up. The operator should replace the missing buckle and test again until the product is qualified before packing it into a box.
