Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically a rapid positioning detection mechanism. Background Technology

[0002] Currently, optical inspection devices are required for product appearance defect detection. In existing technologies, the inspection fixture is typically fixed to an inspection platform. The optical inspection device needs to be moved to align its image acquisition end directly above the fixture's workstation for image acquisition. Furthermore, the light source is mounted on the optical inspection device. With repeated reciprocating movements of the optical inspection device, positional errors can easily occur. These positional errors at the image acquisition end can cause inaccurate illumination by the light source, ultimately resulting in a discrepancy between the image acquired and the actual product, necessitating re-inspection. This method is inefficient and suffers from various problems, including inaccurate image acquisition end positioning.

[0003] Therefore, the inventors of this application propose a rapid positioning and detection mechanism. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a rapid positioning and detection mechanism, which aims to solve the technical problems existing in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid positioning and detection mechanism, comprising a base, a fixture plate, a product support block, a drive mechanism, a lamp body, and a limiting block. The fixture plate is mounted on the base and has a light-transmitting opening (first) through the fixture plate. The lamp body is mounted on the base and is located directly below the light-transmitting opening (first) on the fixture plate. The product support block is slidably mounted on the fixture plate and has a detection station. The detection station has a light-transmitting opening (second) through the product support block. The drive mechanism drives the product support block so that the light-transmitting opening (second) at the detection station aligns with the light-transmitting opening (first) on the fixture plate. The limiting block is located on the side of the fixture plate to restrict the travel of the product support block.

[0006] Furthermore, the fixture plate is provided with a groove, and the product support block is slidably disposed within the groove of the fixture plate.

[0007] Furthermore, the fixture plate is also provided with a light shield, and the opening of the light shield and the light-transmitting opening on the fixture plate are on the same axis.

[0008] Furthermore, the base is provided with a connecting plate and a connecting frame, the fixture plate is mounted on the base via the connecting plate, and the lamp body is mounted on the base via the connecting frame.

[0009] Furthermore, the drive mechanism is mounted on the connecting plate, and the output end of the drive mechanism is provided with a transmission block. The transmission block is provided with a push-pull rod, and the other end of the push-pull rod is connected to the product support block.

[0010] Compared with existing technologies, this invention offers the following advantages: It provides a rapid positioning and detection mechanism. By suspending a fixture plate on a base and placing a lamp directly below the fixture plate, the light-emitting surface of the lamp is aligned with the first light-transmitting opening on the fixture plate. The product support block, driven by a mechanism, aligns the second light-transmitting opening on the detection station with the first light-transmitting opening on the fixture plate, allowing the product to receive light projection. Furthermore, this rapid positioning and detection mechanism includes a limiting block on the side of the fixture plate to restrict the travel of the product support block, ensuring precise positioning of the detection station on the product support block to the predetermined location. This solves the problem in existing technologies where positional errors at the image acquisition end cause incomplete illumination by the light source, resulting in discrepancies between the image acquired and the actual product, necessitating re-inspection.

[0018] 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.

[0019] Please see Figure 1-6 As shown, this utility model provides a technical solution: a rapid positioning and detection mechanism, including a base 1, a fixture plate 2, a product support block 3, a drive mechanism 4, a lamp body 5, and a limiting block 6. The fixture plate 2 is mounted on the base 1 via a connecting plate 12 and has a light-transmitting opening 7 through it. The lamp body 5 is mounted on the base 1 via a connecting frame 13 and is located directly below the light-transmitting opening 7 on the fixture plate 2. The product support block 3 is slidably mounted on the fixture plate 2 and has a detection station 8. The detection station 8 has a light-transmitting opening 9 through it. The drive mechanism 4 drives the connected product support block 3 so that the light-transmitting opening 9 on the detection station 8 is aligned with the light-transmitting opening 7 on the fixture plate 2. The limiting block 6 is located on the side of the fixture plate 2 to limit the travel of the product support block 3.

[0020] Please see Figure 1 As shown, the drive mechanism 4 is mounted on the connecting plate 12. The output end of the drive mechanism 4 is provided with a transmission block 14, and the transmission block 14 is provided with a push-pull rod 15. The other end of the push-pull rod 15 is connected to the product support block 3.

[0021] Please see Figure 2-3 As shown, the fixture plate 2 is also provided with a light shield 11, and the opening of the light shield 11 and the light-transmitting opening 7 on the fixture plate 2 are on the same axis. The purpose of the light shield 11 is to concentrate the light source and irradiate the product 16, so that the appearance of the product 16 is sufficiently illuminated by the light source to improve the detection efficiency.

[0022] Please see Figure 5 As shown, the fixture plate 2 is provided with a sliding groove 10, and the product support block 3 is slidably disposed in the sliding groove 10 of the fixture plate 2.

[0023] This invention suspends the fixture plate 2 on the base 1 and positions the lamp body 5 directly below the fixture plate 2, ensuring that the light-emitting surface of the lamp body 5 is aligned with the light-transmitting opening 7 on the fixture plate 2. The product support block 3, driven by the drive mechanism 4, aligns the light-transmitting opening 9 on the inspection station 8 with the light-transmitting opening 7 on the fixture plate 2, allowing the product to receive light projection. Furthermore, this rapid positioning inspection mechanism includes a limiting block 6 on the side of the fixture plate 2, ensuring that the inspection station 8 on the product support block 3 is precisely positioned at the predetermined location. This solves the problem in existing technologies where positional errors at the image acquisition end cause incomplete illumination by the light source, resulting in discrepancies between the image acquired and the actual product, necessitating re-inspection. This rapid positioning inspection mechanism is used in conjunction with an image acquisition device, which can be mounted on a movable module or fixed in a specific position. When it is necessary to inspect the product appearance, simply drive the product support block 3 to move within the slide groove 10 of the fixture plate 2, so that the inspection station 8 is aligned directly above the acquisition end of the image acquisition device for image acquisition.
