Description

Technical Field

[0001] This utility model belongs to the field of dental implant screw inspection, and in particular relates to a device for detecting defects in dental implant screws. Background Technology

[0002] Inspection of dental implant screws is a crucial step in ensuring the success of dental implant surgery and the long-term stability of the implant. Strict inspection methods and precautions ensure that the screw tightness, dimensional accuracy, and surface quality meet specified standards, thereby protecting the patient's oral health and the lifespan of the implant.

[0003] In existing dental implant screw inspection processes, in addition to slot shape inspection, length and thread defects also need to be detected. However, the positional relationship between the visual inspection camera, light source, and implant screw plays a crucial role in the imaging effect. Current methods determine this relationship by defining the installation position, but due to machining errors, even if the installation position is pre-set during manufacturing, errors will still exist after assembly, making it difficult to obtain optimal imaging results. Furthermore, current defect detection methods require a robotic arm to pick up the implant screw and place it at the inspection station each time, and then remove it from the inspection station to the next process after inspection. This method results in low inspection efficiency, which needs to be improved. Utility Model Content

[0036] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 9 As shown, the implant screw defect detection device provided in this embodiment includes a rotating base 3, clamping members 4, a frame 1, a first adjusting member 5, a visual inspection camera 10, a second adjusting member 6, a light source 2, a positioning member 7, a waste collection member 8, and a qualified product collection member 9. Four clamping members 4, evenly spaced along the circumference of the rotating base 3, are fixed to the rotating end. The first adjusting member 5, the second adjusting member 6, and the positioning member 7 are all fixed to the frame 1. The visual inspection camera 10 is fixed to the adjusting end of the first adjusting member 5, located outside the clamping members 4 with its lens facing the clamping members 4. The light source 2 is fixed to the adjusting end of the second adjusting member 6, located inside the clamping members 4 and opposite to the visual inspection camera 10. The positioning member 7 is located above the clamping member 4 rotated between the visual inspection camera 10 and the light source 2. The waste collection member 8 and the qualified product collection member 9 are spaced apart along the circumference of the rotating base 3, with the waste collection member 8 located between the positioning member 7 and the qualified product collection member 9. In this embodiment, the left side of the rotating seat 3 is the feeding area, the front side is the detection area, the right side is the waste collection area, and the rear side is the qualified product collection area.

[0039] The previous station picks up the dental implant screws and places them in the loading area. The clamping device 4 in the loading area holds the screws in place. The rotating seat 3 rotates 90° counterclockwise. As the rotating seat 3 rotates, the dental implant screws in the loading area are conveyed to the inspection area. A visual inspection camera 10 checks for defects in the screw threads and length. After inspection, the rotating seat 3 continues to rotate 90° counterclockwise, conveying the inspected dental implant screws to the waste collection area. If the inspected dental implant screws are defective, the clamping device 4 releases, and the defective products are collected by the waste collection device 8. If the inspected dental implant screws are qualified, the rotating seat 3 continues to rotate 90° counterclockwise, conveying the qualified product collection area. The clamping device 4 releases, and the qualified products are collected by the qualified product collection device 9, thus completing one full process. The system employs a rotating base 3 in conjunction with a clamping component 4. When the clamping component 4 moves from the current work area to the next, the clamping component 4 from the previous work area moves to the current work area to fill the gap, enabling continuous feeding, inspection, and collection operations, significantly improving inspection efficiency. The vision inspection camera 10 is adjusted via the first adjusting component 5, and the light source 2 is adjusted via the second adjusting component 6. Post-factory adjustment testing ensures optimal forming results and thus good inspection accuracy, resolving the error problems inherent in traditional structural machining. The positioning component 7 positions the implant screws, ensuring they are inspected vertically by the vision inspection camera 10, further improving inspection accuracy.

[0040] The rotating base 3 includes a base 31, a hollow rotating platform 32, a motor 33, a turntable 34, a support 35, and an annular plate 36.

The annular plate 36 is fixed to the top of the supports 35. The clamping member 4 is fixed to the annular plate 36. During rotation, the motor 33 drives the hollow rotating platform 32, which in turn drives the turntable 34 to rotate, causing the supports 35 to rotate, which in turn drives the annular plate 36 to rotate, and in turn drives the clamping member 4 to rotate. The hollow rotating platform 32 allows for precise control and positioning of the rotation speed and angle of the annular plate 36, ensuring the efficient operation of the production line.

[0041] The clamping component 4 includes a Z-axis slide 41, a first mounting plate 42, a bolt 43, a thumb cylinder 44, and a gripper 45. The bottom of the annular plate 36 is fixed with the Z-axis slide 41, the sliding end of which has a threaded hole 47. The first mounting plate 42 has a strip hole 46. The bolt 43 passes through the strip hole 46 and is inserted into the threaded hole 47 to fix the first mounting plate 42 to the sliding end of the Z-axis slide 41. The thumb cylinder 44 is fixed to the first mounting plate 42, and the gripping end of the thumb cylinder 44 is detachably fixed with a gripper 45. The end of the gripper 45 has a gripping groove 48. The clamping height is adjusted by the Z-axis slide 41, and the left and right positions of the clamping are adjusted by the strip hole 46, the threaded hole 47, and the bolt 43. In this way, in conjunction with the first adjusting component 5 and the second adjusting component 6, the positional relationship between the visual inspection camera 10, the light source 2, and the implant screw can be adjusted to achieve the best imaging effect. The clamping groove 48 ensures stable clamping of the dental implant screw.

[0042] The system also includes a leveling block 11. Each annular plate 36 above the thumb cylinder has a clearance hole 37. A leveling block 11 is fixed between adjacent clearance holes 37. The top of the gripper 45 passes through the clearance hole 37 and is located above the leveling block 11. The top surface of the leveling block 11 is flat. By setting the leveling block 11, the bottom surface of the implant screw is positioned, and the top surface of the implant screw is positioned in conjunction with the positioning component 7, ensuring that the implant screw is in a vertical position for accurate imaging detection by the visual inspection camera 10.

[0043] The waste collection component 8 and the qualified product collection component 9 have the same structure, both including: a first mounting frame 891, a solenoid valve 892, a hose 893, a collection pipe 894, a second mounting frame 895, and a collection frame 896. The first mounting frame 891 is set on the frame 1. The bottom of the first mounting frame 891 is equipped with a solenoid valve 892. The output end of the solenoid valve 892 is fixedly connected to the hose 893. The input end of the solenoid valve 892 is connected to the air source. The collection pipe 894 is set on the second mounting frame 895. The collection frame 896 is set below the collection pipe 894. The feed end of the collection pipe 894 is located outside the clamping end of the clamping component 4. The air outlet end of the hose 893 is located inside the clamping end of the clamping component 4. The feed end of the collection pipe 894 and the air outlet end of the hose 893 are arranged opposite to each other. When material collection is needed, the solenoid valve 892 is opened, and air from the air source is blown through the hose 893 toward the implant screw, blowing the implant screw to the collection pipe 894, and then falling through the collection pipe 894 into the collection frame 896 for collection. The outlet position of the hose 893 can be changed by adjusting the setting according to needs.

[0044] The first adjusting component 5 includes a Y-axis slide 51, an X-axis slide 52, a first arc-shaped slide 53, and a first mounting base 54. The Y-axis slide 51 is fixed to the frame 1.

The slide cylinder 72 is fixed to the Z-axis sliding end of the XYZ axis slide 71, and the stop 73 is fixed to the bottom end of the slide cylinder 72. The stop 73 is located above the clamping component 4, and its bottom surface is flat. In this embodiment, the XYZ axis slide 71 is model XYZEG40. By adjusting the position of the stop 73 in all directions (front, back, left, right, up, down) using the XYZ axis slide 71, the stop 73 is positioned directly above the implant screw. The slide cylinder 72 extends, causing the stop 73 to move downwards until the implant screw is positioned on the stop 73. The flat bottom surface of the stop 73 and the flat top surface of the leveling block ensure that the implant screw 43 is detected in a vertical position, improving detection accuracy.

[0047] The rotating base 3 also includes a base 38, an electrical slip ring 39, and a fixing frame 310. The base 38 is fixed to the middle of the turntable 34, and the electrical slip ring 39 is fixed to the top of the base 38.
