Description

Technical Field

[0001] This utility model relates to the field of inspection tooling technology, specifically a guide groove size inspection tooling based on machine vision. Background Technology

[0002] Sealing strip guide grooves are key components of automotive sealing systems. Their dimensional accuracy directly affects sealing performance. They are usually made of elastic materials and are widely used in various mechanical equipment and industrial scenarios. In automobiles, sealing strip guide grooves are mainly used to improve sealing performance, reduce frictional resistance, and reduce noise. Whether the guide groove is properly installed needs to be inspected.

[0003] The existing inspection process is not convenient to adjust according to the thickness of the sealing strip during use. When the gap is large, the sealing strip is prone to shaking, which reduces the accuracy of the inspection. When the gap is small, it is difficult to place the sealing strip on the tooling for inspection. Furthermore, it is not convenient to remove the sealing strip from the tooling after inspection, which reduces the inspection efficiency.

[0004] Based on this, a machine vision-based guide groove dimension inspection fixture is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[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 1-4 As shown, the guide groove size inspection fixture based on machine vision includes two bases 1, and a support 2 is fixedly installed on the top of each of the two bases 1. A placement frame 3 is fixedly connected to the top of the two support 2, and an installation groove 4 is opened on the top of the placement frame 3.

[0027] The mounting slot 4 is equipped with an adjustment mechanism 5, and the placement rack 3 is equipped with a discharge mechanism 6 on one side.

[0028] In this embodiment, the adjustment mechanism 5 can be adjusted according to the thickness of the sealing strip, so that the sealing strip can be stably placed above the placement rack 3 for testing. This avoids the situation where the detection error increases due to excessive gap or the sealing strip is difficult to insert due to insufficient gap. The discharge mechanism 6 facilitates the removal of qualified sealing strips from the inside of the placement rack 3, thus providing a convenient unloading function and improving the efficiency of sealing strip guide groove testing.

[0029] In one embodiment, such as Figure 1 and Figure 4 As shown, the adjustment mechanism 5 includes a lead screw 51, which is rotatably installed inside the mounting groove 4. One end of the lead screw 51 passes through the placement frame 3 and is connected to a knob 52. An adjustment plate 53 is threadedly connected to the outside of the lead screw 51. By rotating the knob 52, the lead screw 51 is driven to rotate, and the rotation of the lead screw 51 drives the adjustment plate 53 to move, which facilitates adjustment according to the thickness of the sealing strip and improves adaptability.

[0030] In one embodiment, such as Figure 1 and Figure 3As shown, the discharge mechanism 6 includes a motor 61, which is fixedly mounted on one side of the placement frame 3. A gear 62 is keyed to the output end of the motor 61. A baffle 63 is fixedly connected to one end of the gear 62. An ejector assembly is provided outside the gear 62, including a rack 64 meshing with the outside of the gear 62. An ejector 65 is fixedly mounted to one end of the rack 64. The top of the placement frame 3 has symmetrically arranged sliding grooves 17. The bottom of the placement frame 3 is slidably mounted with the ejector 65 through the sliding grooves 17, and the ejector 65 is fixedly connected to the rack 64. A soft pad 66 is glued to the top of the ejector 65. A limiter is provided at the bottom of the placement frame 3. The component includes a limiting member 67, which is fixedly installed at the bottom of the placement frame 3. The rack 64 is slidably installed with the limiting member 67. When the sealing strip guide groove is qualified, the motor 61 drives the gear 62 and the baffle 63 to rotate. The baffle 63 rotates to be horizontal with the placement frame 3. At the same time, the gear 62 rotates and drives the rack 64 to move upward. The rack 64 drives the ejector 65 to move upward, effectively ejecting the sealing strip from the inside of the placement frame 3, which facilitates the unloading process and improves the efficiency of the inspection. After the unloading mechanism 6 rotates, it is convenient to place the qualified sealing strip above the unloading rod 16. If the sealing strip guide groove is not qualified, the motor 61 does not work, the position of the sealing strip is manually adjusted, and the inspection is repeated.

[0031] In one embodiment, such as Figure 1 and Figure 2 As shown, a rotary cylinder 7 is fixedly installed on one side of each of the two support members 2, and a clamping member 8 is fixedly installed on the output end of each of the two rotary cylinders 7. Switches 9 are symmetrically fixedly installed on the other side of the placement frame 3. After the sealing strip is placed inside the placement frame 3, the two switches 9 are pressed at the same time, and the two rotary cylinders 7 work to drive the clamping member 8 to rotate, thus fixing the corner of the sealing strip.

[0032] In one embodiment, such as Figure 1 and Figure 2 As shown, a protective shell 10 is fixedly installed between each of the two support members 2 and the placement frame 3. A detection camera 11 is installed inside each of the two protective shells 10. An indicator light 12 is fixedly installed on one side of the placement frame 3. The detection camera 11 takes a picture of the corner of the sealing strip and compares the picture with the comparison picture to determine whether the sealing strip is qualified. If it is not qualified, the indicator light 12 flashes an alarm.

[0033] In one embodiment, such as Figure 1 and Figure 2As shown, a support rod 13 is fixedly installed on the top of each of the two bases 1, and an installation rod 14 is fixedly installed between the two support rods 13. Two mounting seats 15 are fixedly installed on one side of the installation rod 14, and a feeding rod 16 is rotatably installed on the outside of each of the two mounting seats 15. Qualified sealing strips are placed on the two feeding rods 16 and slide down due to gravity, which facilitates the conveying of qualified sealing strips.

[0034] The above embodiments disclose a machine vision-based guide groove size inspection fixture. Rotating knob 52 drives lead screw 51 to rotate, which in turn moves adjusting plate 53, facilitating adjustment based on the thickness of the sealing strip. After the sealing strip is placed inside the placement frame 3, pressing two switches 9 simultaneously activates two rotary cylinders 7, causing clamping member 8 to rotate and fix the corner of the sealing strip. Inspection camera 11 captures images of the corner of the sealing strip, comparing the captured image with a comparison image to determine if the sealing strip is qualified. When the sealing strip guide groove inspection is qualified, motor 61 drives gear 62 and baffle 63 to rotate. Baffle 63 rotates to be horizontal with the placement frame 3, while gear 62 rotates, causing rack 64 to move upwards. Rack 64 then moves ejector 65 upwards, effectively ejecting the sealing strip from inside the placement frame 3 for easier unloading and improved inspection efficiency. If the sealing strip is unqualified, indicator light 12 flashes an alarm. The position of the sealing strip is manually adjusted, and the inspection is repeated. If indicator light 12 still flashes, the sealing strip is unqualified.

[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.
