Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, and in particular to a hardware appearance inspection device. Background Technology

[0002] Hardware parts refer to various components made from metals such as gold, silver, copper, iron, and tin through processing, casting, forging, and other techniques. They are widely used in many fields such as machinery manufacturing, construction, electronics, automobiles, and aerospace. Visual inspection of hardware parts is a crucial step in ensuring their quality. This involves checking the surface for scratches, abrasions, dents, and other mechanical damage, as well as casting or welding defects such as sand holes, air pockets, and cracks. It also involves measuring key dimensions such as length, width, thickness, hole diameter, and outer diameter to ensure they are within specified tolerances, thereby guaranteeing the hardware parts meet quality requirements.

[0003] Currently, the inspection of hardware parts typically involves capturing images of the parts using industrial cameras, followed by image processing algorithms to analyze and process the images for automated inspection. When simultaneously inspecting the top surface and aperture of the hardware part, existing devices often require two cameras at different heights. The higher camera can clearly focus on the top surface, capturing a complete and clear image for detecting surface scratches, blemishes, discoloration, and other defects. The lower camera can more accurately focus on the aperture, clearly revealing its detailed features such as dimensional accuracy, roundness, and inner wall roughness, ensuring accurate aperture inspection. However, using two cameras in existing devices results in high equipment costs and necessitates switching between cameras or image fusion, impacting inspection efficiency.

[0004] Therefore, to address the aforementioned issues, a hardware appearance inspection device has been developed that can simultaneously inspect the upper surface and aperture of hardware parts using only a single camera, saving equipment costs and improving inspection efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the existing devices in the background art, the present invention provides a hardware appearance inspection device that can simultaneously inspect the upper surface and aperture of hardware parts using only a single camera, thereby saving equipment costs and improving inspection efficiency.

[0006] The technical solution is as follows: A hardware appearance inspection device includes a base, a first motor, a rotating table, a placement seat, a mounting column, a contact ball, a first spring, a stand, a camera, and a lifting assembly. The first motor is connected to the upper side of the middle of the base, and the rotating table is connected to the output shaft of the first motor. Multiple placement seats are slidably connected to the rotating table, and each placement seat is connected to the rotating table by a first spring. Each placement seat is connected to the lower part of a mounting column, and each mounting column is rotatably connected to a contact ball. A stand is connected to the left side of the base, and a camera is connected to the upper part of the stand. A lifting assembly is provided on the upper left side of the base.

[0007] As a further preferred embodiment, the lifting assembly includes a second motor and a lifting wheel. The second motor is connected to the upper left side of the base, and the lifting wheel is connected to the output shaft of the second motor. All contact balls can contact the lifting wheel.

[0008] As a further preferred option, the lifting wheel is a cam structure.

[0009] As a further preferred option, supplementary lighting is also included, with supplementary lighting installed on the support frame.

[0010] As a further preferred option, a material feeding assembly is also included, which is located on the front side of the base.

[0011] As a further preferred embodiment, it also includes a positioning pin and a second spring. The positioning pin is slidably connected to the middle of the upright, and the positioning pin can engage with the rotating table. The second spring connects the positioning pin and the upright.

[0012] The beneficial effects of this utility model are as follows: This utility model uses the output shaft of the second motor to drive the lifting wheel to rotate, and the rotation of the lifting wheel lifts the contact ball, thereby driving the hardware to move upward and adjusting the height of the hardware. This allows for the simultaneous detection of the upper surface and aperture of the hardware using only a single camera, saving equipment costs and improving detection efficiency.

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0019] A hardware component appearance inspection device, such as Figures 1-4 As shown, the device includes a base 1, a first motor 2, a rotating platform 3, a placement seat 4, a mounting column 5, a contact ball 6, a first spring 7, a stand 8, a camera 9, and a lifting assembly. The first motor 2 is connected to the upper middle part of the base 1. The rotating platform 3 is connected to the output shaft of the first motor 2. Twelve placement seats 4 are slidably connected to the rotating platform 3. Each placement seat 4 is connected to the rotating platform 3 by a first spring 7. Each placement seat 4 is connected to the lower part of a mounting column 5. Each mounting column 5 is rotatably connected to a contact ball 6. The stand 8 is connected to the left side of the base 1. The camera 9 is connected to the upper part of the stand 8. A lifting assembly is provided on the upper left side of the base 1. The placement seats 4 are used to place the hardware parts to be inspected. The rotation of the first motor 2's output shaft drives the rotating platform 3 to rotate. The rotation of the rotating platform 3 drives the placement seats 4 to move, thereby moving the hardware parts to move sequentially to below the camera 9. The camera 9 inspects the appearance and aperture of the upper surface of the hardware parts.

[0020] The lifting assembly includes a second motor 12 and a lifting wheel 13. The second motor 12 is connected to the upper left side of the base 1, and the lifting wheel 13 is connected to the output shaft of the second motor 12. The contact balls 6 can all contact the lifting wheel 13. When the placement seat 4 moves the mounting column 5 and the contact balls 6 above the lifting wheel 13, the upper surface of the hardware is aligned with the focal plane of the camera 9. The appearance of the upper surface of the hardware can be inspected by the camera 9. Then, the output shaft of the second motor 12 rotates to drive the lifting wheel 13 to rotate. The rotation of the lifting wheel 13 lifts the contact balls 6, causing them to move the mounting column 5 and the placement seat 4 upward. The first spring 7 is compressed, thereby moving the hardware upward so that the aperture of the hardware is aligned with the focal plane of the camera 9. The aperture of the hardware can be inspected by the camera 9. Thus, only a single camera 9 can be used to inspect the upper surface and aperture of the hardware at the same time.

[0021] The lifting wheel 13 is a cam structure;

[0022] It also includes a supplementary light 10, which is installed on the stand 8. During the inspection process, the supplementary light 10 provides supplementary lighting to the hardware parts to improve the inspection clarity.

[0023] It also includes a material feeding assembly 11, which is provided on the front side of the base 1 to export the hardware parts after the inspection is completed.

[0024] It also includes a positioning pin 14 and a second spring 15. The positioning pin 14 is slidably connected in the middle of the upright 8. The positioning pin 14 can be engaged with the rotating table 3. The positioning pin 14 and the upright 8 are connected by a second spring 15. Under the action of the second spring 15, the positioning pin 14 can engage and limit the rotating table 3, so that the rotating table 3 is positioned during rotation, ensuring the accurate position of the hardware on the placement seat 4.

[0025] In use, this invention first needs to be installed in the operating area. Then, the hardware components to be tested are transported to the placement seat 4. The output shaft of the first motor 2 rotates, driving the rotating table 3 to rotate. The rotation of the rotating table 3 moves the placement seat 4, thereby moving the hardware components sequentially to below the camera 9. Under the action of the second spring 15, the positioning pin 14 can engage and limit the rotating table 3, ensuring its positioning during rotation and guaranteeing the accurate placement of the hardware components on the placement seat 4. When the placement seat 4 moves the mounting column 5 and contact ball 6 above the lifting wheel 13, the upper surface of the hardware component is aligned with the focal plane of the camera 9, allowing for image capture. Machine 9 inspects the appearance of the upper surface of the hardware part, and then drives the lifting wheel 13 to rotate through the output shaft of the second motor 12. The rotation of the lifting wheel 13 lifts the contact ball 6, causing it to move the mounting column 5 and the placement seat 4 upward. The first spring 7 is compressed, thereby moving the hardware part upward, so that the hole of the hardware part is aligned with the focal plane of the camera 9. The hole of the hardware part can then be inspected by the camera 9. Thus, only a single camera 9 can be used to inspect the upper surface and hole of the hardware part at the same time. During the inspection, the hardware part is illuminated by the supplementary light 10 to improve the inspection clarity. After the inspection is completed, the hardware part can be exported under the action of the feeding assembly 11.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
