Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment technology, and in particular to a rotating shaft visual rapid inspection clamping fixture. Background Technology

[0002] Visual inspection uses machines to replace human eyes for measurement and judgment. It involves converting the captured target into an image signal using machine vision products, transmitting it to a dedicated image processing system, and then converting it into a digital signal based on pixel distribution, brightness, color, and other information to obtain data feedback and understand the product's qualification status. With the promotion of foldable phones, their market is becoming increasingly widespread. The hinge of a foldable phone is a key component to ensure its lifespan. After the hinge is processed, there are corresponding technical indicators for the cleanliness of the hinge surface. However, due to the small size of the hinge, manual inspection methods cannot meet the inspection requirements. This necessitates the use of visual inspection devices. The stability during the inspection process will affect the inspection effect of the hinge. Therefore, it is necessary to use a fixture to improve the inspection stability of the hinge. Thus, a rapid visual inspection fixture for hinges is needed. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a rotating axis vision rapid inspection fixture to solve the stability problem in the rotating axis vision inspection process in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A rotating vision rapid inspection fixture includes:

[0006] A detection base is provided, with a camera assembly on the upper side of the detection base and a rotating shaft positioning plate on the detection base, the rotating shaft positioning plate being located below the camera working surface of the camera assembly;

[0007] A pivot limiting plate is slidably connected inside the pivot positioning plate along the front-back direction. A pivot positioning groove is provided inside the pivot limiting plate. A flared pivot guide groove is provided on the upper side of the pivot positioning groove. The opening of the pivot guide groove faces upward. A light shield is provided on the pivot positioning plate. The light shield covers the output surface of the camera component.

[0008] To achieve the above technical solution, a rotating shaft positioning plate is installed below the camera working surface of the camera assembly. This allows for the positioning of the rotating shaft's detection position, ensuring the stability of each set of rotating shafts during detection. A rotating shaft limiting plate is slidably connected within the rotating shaft positioning plate in the front-to-back direction. The position of the rotating shaft limiting plate can be adjusted according to detection needs, thus meeting the detection requirements of rotating shafts of different lengths. The rotating shaft positioning groove provides limiting treatment during rotating shaft detection, preventing displacement deviation of the rotating shaft during the detection process. The trumpet-shaped rotating shaft guide groove provides guidance when the rotating shaft is manually placed into the rotating shaft positioning groove, preventing damage to the rotating shaft surface during placement.

[0009] In one embodiment of the present invention, a limiting plate groove is provided in the rotating shaft positioning plate, the rotating shaft limiting plate slides in the front-back direction with the limiting plate groove, a limiting through hole is provided on the front side of one side of the limiting plate groove, a limiting bolt is threaded in the limiting through hole, and the rear end of the limiting bolt is rotatably connected to the rotating shaft limiting plate.

[0010] To achieve the above technical solution, a limiting bolt is threaded into the limiting through hole, and after the limiting bolt passes through the limiting plate groove, it is connected to the rotating shaft limiting plate and rotatably connected to the rotating shaft limiting plate. By rotating the limiting bolt, the position of the rotating shaft limiting plate in the front-to-back direction within the limiting plate groove is adjusted.

[0011] In one embodiment of the present invention, the camera assembly includes a camera and a lifting base. The lifting base is located on one side of the detection platform. The camera is slidably connected to the lifting base and is liftable. The lifting base is provided with a lifting drive component to drive the camera to move up and down.

[0012] To achieve the above technical solution, a lifting drive component is installed inside the lifting base, which can drive the camera to move up and down, thereby meeting the needs of adjusting the camera height during visual inspection.

[0013] In one embodiment of the present invention, the lifting base is provided with two sets of symmetrical lifting slide rails, a lifting base plate is slidably connected on the lifting slide rails, and four sets of mutually symmetrical lifting sliders are provided between the lifting base plate and the lifting slide rails to improve the positioning stability of the lifting base plate on the lifting slide rails.

[0014] To achieve the above technical solution, in order to ensure the stability of the camera's lifting and lowering motion, a stable limiting component is needed to cooperate during the lifting and lowering motion. By setting four sets of mutually symmetrical lifting sliders between the lifting base plate and the lifting slide rail, the positioning stability of the lifting base plate on the lifting slide rail can be further improved, thereby improving the stability of the camera's lifting and lowering motion and avoiding shaking during the camera's lifting and lowering process.

[0015] In one embodiment of this utility model, the camera is detachably connected to the lifting base plate.

[0016] Implementing the above technical solution facilitates the maintenance and upkeep of the camera.

[0017] In one embodiment of this utility model, a light-blocking cloth is wrapped between the camera and the light shield.

[0018] To achieve the above technical solution, the setting of the light-blocking cloth can meet the displacement requirements of the camera while reducing the problem of scattering light during the detection process.

[0019] As described above, the rotating shaft visual rapid inspection clamping fixture of this utility model has the following beneficial effects: by setting a rotating shaft positioning plate below the camera working surface of the camera assembly, the detection position of the rotating shaft can be positioned, thereby ensuring the stability of each group of rotating shafts during inspection. By slidably connecting a rotating shaft limiting plate in the rotating shaft positioning plate along the front-back direction, the position of the rotating shaft limiting plate can be adjusted according to the inspection needs, thereby meeting the inspection requirements of rotating shafts of different lengths. The setting of the rotating shaft positioning groove can provide limiting treatment for rotating shaft inspection, avoiding displacement deviation of the rotating shaft during the inspection process. The trumpet-shaped rotating shaft guide groove can provide a guiding effect when the rotating shaft is manually placed into the rotating shaft positioning groove, avoiding damage to the surface of the rotating shaft when placing it.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] By setting a rotating shaft positioning plate 2 below the camera working surface of the camera assembly, the detection position of the rotating shaft can be positioned, thereby ensuring the stability of each group of rotating shafts during detection. By slidably connecting a rotating shaft limiting plate 3 in the rotating shaft positioning plate 2 along the front-back direction, the position of the rotating shaft limiting plate 3 can be adjusted according to the detection needs, thereby meeting the detection requirements of rotating shafts of different lengths. The setting of the rotating shaft positioning groove 4 can provide limiting treatment for the rotating shaft during detection, avoiding displacement deviation of the rotating shaft during the detection process. The trumpet-shaped rotating shaft guide groove 5 can provide a guiding function when the rotating shaft is manually placed into the rotating shaft positioning groove 4, avoiding damage to the surface of the rotating shaft when placing it.

[0029] The rotating shaft positioning plate 2 is provided with a limiting plate groove 7. The rotating shaft limiting plate 3 slides in the limiting plate groove 7 along the front and back direction. A limiting through hole is provided on the front side of one side of the limiting plate groove. A limiting bolt 8 is threaded in the limiting through hole. The rear end of the limiting bolt 8 is rotatably connected to the rotating shaft limiting plate 3.

[0030] A limiting bolt 8 is threaded into the limiting through hole, and after the limiting bolt 8 passes through the limiting plate groove, it is connected to the rotating shaft limiting plate 3 and rotatably connected to the rotating shaft limiting plate 3. By rotating the limiting bolt 8, the position of the rotating shaft limiting plate 3 in the front-back direction in the limiting plate groove 7 can be adjusted.

[0031] The camera assembly includes a camera 9 and a lifting base 10. The lifting base is located on one side of the detection platform 1. The camera 9 is slidably connected to the lifting base and can be raised and lowered. A lifting drive component 11 is provided inside the lifting base to drive the camera 9 to move up and down. By providing a lifting drive component 11 inside the lifting base, the camera 9 can be moved up and down using the lifting drive component 11, thereby meeting the height adjustment of the camera 9 during the visual inspection process to meet the inspection requirements.

[0032] The lifting base 10 is provided with two sets of symmetrical lifting slide rails 12. A lifting base plate 13 is slidably connected to the lifting slide rails 12. Four sets of mutually symmetrical lifting sliders 14 are provided between the lifting base plate 13 and the lifting slide rails 12 to improve the positioning stability of the lifting base plate 13 on the lifting slide rails 12. In order to ensure the stability of the camera 9 during the lifting movement, a stable limiting component is required during the lifting movement. By providing four sets of mutually symmetrical lifting sliders 14 between the lifting base plate 13 and the lifting slide rails 12, the positioning stability of the lifting base plate 13 on the lifting slide rails 12 can be further improved, thereby improving the stability of the lifting movement of the camera 9 and avoiding shaking during the lifting of the camera 9.

[0033] The camera 9 is detachably connected to the lifting base plate 13, which facilitates the maintenance of the camera 9. A light-shielding cloth 15 is wrapped between the camera 9 and the light shield 6. The light-shielding cloth 15 can meet the displacement requirements of the camera 9 while reducing the scattering problem during the detection process.

[0034] This invention features a rotating shaft positioning plate located below the camera working surface of the camera assembly. This allows for the positioning of the rotating shaft at its detection position, ensuring stability during the detection of each set of rotating shafts. A rotating shaft limiting plate, slidably connected within the positioning plate in the front-to-back direction, allows for adjustment of its position according to detection needs, accommodating rotating shafts of different lengths. The rotating shaft positioning groove provides limiting during detection, preventing displacement deviation. Furthermore, the trumpet-shaped rotating shaft guide groove guides the rotating shaft as it is manually placed into the positioning groove, preventing damage to the shaft surface during placement.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model.
