Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of image recognition devices, and in particular to a flat plate hole position measuring device. Background Technology
[0002] Flat products have holes on both the long and short sides, so visual inspection of these holes can quickly screen out defective products. Conventional visual inspection uses a single vision camera to measure the holes on all four sides of the product by rotating the product four times. This is inefficient, and the frequent switching of position and orientation requires refocusing, which reduces the lifespan of the vision camera and decreases measurement accuracy. Utility Model Content
[0003] This invention provides a flat plate hole position measuring device, which is simple and practical, and highly efficient in measuring the hole positions on the long and short sides of a product.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a flat plate hole position measuring device, comprising a mounting plate, a stage assembly disposed in the middle of the mounting plate, and a set of camera assemblies symmetrically disposed on both sides of the stage assembly. The stage assembly includes a carrier, which includes a mounting base, a rotary cylinder disposed on the mounting base, and a light-transmitting carrier plate for mounting products disposed on the output shaft of the rotary cylinder. A gap is provided between the light-transmitting carrier plate and the upper end surface of the mounting base. An LED bead is disposed on the upper end surface of the mounting base. The camera assembly includes an X-axis linear module, an X-axis slider, and a vision camera disposed on the X-axis slider. The lens of the vision camera faces the carrier.
[0005] In the above solution, the product is placed on a light-transmitting carrier plate and rotated by a rotary cylinder. Generally, it's necessary to measure the hole positions on both sides of the product's long and short sides; therefore, the rotation is typically set to 90 degrees back and forth. In this invention, two symmetrically designed vision cameras on both sides of the platform can measure the product on the light-transmitting carrier plate. The long and short sides can be measured separately before and after the product rotates 90 degrees, improving efficiency. In this invention, LEDs illuminate the interior of the product placed on the carrier plate, facilitating the acquisition of hole positions by the vision cameras.
[0006] In one embodiment, the vision camera includes a housing, within which a Z-axis lifting module is provided, and the lens is mounted on the Z-axis lifting module.
[0007] In the above solution, the visual camera of this utility model has a height adjustment function and a wider range of applications.
[0008] In one embodiment, the platform assembly includes a Y-axis linear module and a Y-axis slider, with the carrier mounted on the Y-axis slider.
[0009] In one embodiment, the camera assembly has two X-axis linear modules, which are parallel and spaced apart.
[0010] In the above solution, each camera assembly includes two vision cameras, corresponding to the measurement positions of the long side and the short side, respectively. Since the two camera assemblies are symmetrically designed, during long side measurement, two vision cameras simultaneously measure both sides of the long side. The product is then transported via a Y-axis linear module to another pair of vision cameras for short side measurement. This invention uses four vision cameras to measure both the long and short sides of the product. Compared to the frequent switching between two vision cameras for long and short side measurement, four vision cameras corresponding to both measurements eliminate the need for frequent focal length adjustments during long or short side measurement, extending the lifespan of the vision cameras. Furthermore, the lack of frequent camera adjustments results in higher data accuracy. Attached Figure Description

[0014] 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.
[0015] Please see Figures 1 to 3The technical solution of this utility model is a flat plate hole position measuring device, including a mounting plate 1, a platform assembly 2 disposed in the middle of the mounting plate 1, and a set of camera assemblies 3 symmetrically disposed on both sides of the platform assembly 2. The platform assembly 2 includes a carrier 4, the carrier 4 including a mounting base 5, a rotary cylinder 6 disposed on the mounting base 5, and a light-transmitting carrier plate 8 for mounting a product 7 disposed on the output shaft of the rotary cylinder 6. A gap is provided between the light-transmitting carrier plate 8 and the upper end surface of the mounting base 5. An LED bead 9 is disposed on the upper end surface of the mounting base 5. The camera assembly 3 includes an X-axis linear module 10, an X-axis slider 11, and a vision camera 12 disposed on the X-axis slider 11. The lens 13 of the vision camera 12 faces the carrier 4.
[0016] In the above scheme, product 7 is placed on the light-transmitting carrier plate 8. The product 7 can be rotated by the rotary cylinder 6. Generally, it is necessary to measure the hole positions on both sides of the long and short sides of product 7; therefore, the rotation is typically set to 90 degrees back and forth. In this invention, two symmetrically designed vision cameras 12 on both sides of the platform 4 can measure product 7 on the light-transmitting carrier plate 8. When product 7 rotates 90 degrees, the hole positions on the long and short sides can be measured separately, improving efficiency. In this invention, the light emitted by the LED bead 9 shines through the light-transmitting carrier plate 8, illuminating the interior of product 7 placed on the light-transmitting carrier plate 8, facilitating the acquisition of hole positions by the vision camera 12.
[0017] In one embodiment, the vision camera 12 includes a housing 14, a Z-axis lifting module 15 is provided inside the housing 14, and the lens 13 is disposed on the Z-axis lifting module 15.
[0018] In the above solution, the visual camera 12 of this utility model has a height adjustment function and a wider range of applications.
[0019] In one embodiment, the platform assembly 2 includes a Y-axis linear module 16 and a Y-axis slider 17, and the carrier 4 is disposed on the Y-axis slider 17.
[0020] In one embodiment, the camera assembly 3 has two X-axis linear modules 10, which are parallel and spaced apart.
[0021] In the above scheme, in this utility model, each camera assembly 3 includes two vision cameras 12, corresponding to the measurement positions of the long side and the short side respectively. In addition, the two sets of camera assemblies 3 are symmetrically designed. Therefore, when measuring the long side, two vision cameras measure both sides of the long side simultaneously. Subsequently, the product 7 is transported to the other pair of vision cameras 12 via the Y-axis linear module 16 for short side measurement. This utility model designs four vision cameras 12 to measure the long side and short side of the product 7. Compared with the frequent switching between the long side and short side measurements performed by only two vision cameras, four vision cameras corresponding to the long side and short side measurements respectively do not require frequent adjustment of the focal length when switching between long side and short side measurements, thus extending the life of the vision cameras. In addition, the vision cameras do not need frequent adjustment, so the data accuracy is also higher.
