Description

A positioning structure based on AOI detector

Technical Field

The utility model relates to the technical field of positioning structures, in particular to a positioning structure based on an AOI detector.

Background Art

The full name of AOI in Chinese is automatic optical inspection, which is a device that detects common defects encountered in welding production based on optical principles. AOI is a new type of testing technology that has just emerged, but it has developed rapidly, and many manufacturers have launched AOI testing equipment. During automatic testing, the machine automatically scans the PCB through a camera, collects images, compares the tested solder joints with qualified parameters in the database, and checks the defects on the PCB through image processing, and displays/marks the defects through a display or automatic mark for maintenance personnel to repair. In order to prevent the detector from moving during use, the detector housing is usually fixed to the surface of the wall with bolts. When the detector housing needs to be disassembled, the bolts need to be removed. The process of disassembling and installing the bolts will consume a lot of time, which is easy to cause the problem of reducing the efficiency of disassembly and installation of the detector housing, and there are restrictions on the use of the detector, which is not flexible and convenient. At the same time, the machine body will vibrate during operation or on the ground, affecting the detection accuracy. Therefore, a positioning structure based on AOI detector is proposed here to solve the above problems.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Please refer to Figures 1 to 4. The utility model provides a technical solution: a positioning structure based on an AOI detector, including a body 1, a fixing frame 2, and a mounting frame 3. The fixing frame 2 is fixedly mounted on the bottom of the body 1, and the mounting frame 3 is mounted on the surface of the fixing frame 2. A servo motor 4 is fixedly mounted on one end of the mounting frame 3. A bidirectional lead screw 5 is fixedly mounted on the output shaft of the servo motor 4. The left and right sides of the outer surface of the bidirectional lead screw 5 are both threadedly connected with a screw sleeve 6. The front and rear sides of the screw sleeve 6 are both fixedly mounted with a limiting rod 7. A sliding groove adapted to the limiting rod 7 is opened on the inner side of the mounting frame 3. The limiting rod 7 can be used to limit the screw sleeve 6 so that the screw sleeve 6 It is more stable when moving to prevent it from rotating when moving. A driving frame 8 is installed on the upper surface of the screw sleeve 6, and a driving shaft 9 is installed on the other end of the driving frame 8. A supporting leg 10 is installed on the outer surface of the driving shaft 9. A driving groove is opened inside the supporting leg 10. The upper and lower ends of the driving groove are arc-shaped. The driving shaft 9 is in the driving groove, which can make the driving shaft 9 smoother and reduce its friction to avoid jamming. After the supporting leg 10 is expanded, the extending leg 16 is triangular with the body 1 and the ground, which can improve the stability of the body 1. A mounting frame 11 is installed on the other end of the supporting leg 10, and the mounting frame 11 is mounted on the surface of the body 1.

Please refer to Figures 3, 4 and 5. A damping column 12 is installed on one side of the mounting frame 11, and a limiting block 13 is installed on the other end of the damping column 12. The diameter of the limiting block 13 is larger than the diameter of the damping column 12. The limiting block 13 can be used to limit the extension sleeve 15 to prevent the extension sleeve 15 from detaching from the outer surface of the damping column 12. The buffer spring 14 is connected to the extension sleeve 15. The outer surface of the damping column 12 is provided with a buffer spring 14. The elastic force provided by the buffer spring 14 can be used to limit the extension leg 16 so that the extension leg 16 is always in contact with the ground. The outer surface of the damping column 12 is movably installed with an extension sleeve 15. A buffer groove is provided inside the extension sleeve 15. The buffer groove provided inside the extension sleeve 15 is adapted to the limit block 13, which can provide sufficient buffer stroke for the extension leg 16 to prevent interference. The other end of the extension sleeve 15 is installed with an extension leg 16. The bottom of the extension leg 16 is installed with a roller 17. The roller 17 is used to facilitate the movement of the extension leg 16 on the ground and reduce the friction between the extension leg 16 and the ground.

Please refer to Figures 3 and 4. A positioning frame 18 is installed on the lower surface of the screw sleeve 6, and electric telescopic rods 19 are fixedly installed on the left and right sides of the body 1. An anti-deflection pad 20 is fixedly installed on the output shaft of the electric telescopic rod 19. A through groove compatible with the anti-deflection pad 20 is opened in the middle of the positioning frame 18. The mutual interference between the positioning frame 18 and the anti-deflection pad 20 can assist the servo motor 4 in positioning the screw sleeve 6.

To sum up, when using the positioning structure based on the AOI detector, the user first needs to start the servo motor 4 to drive the bidirectional screw 5 to rotate, so that the bidirectional screw 5 drives the screw sleeve 6, and the screw sleeve 6 drives the drive frame 8 to move, so that the drive frame 8 drives the drive shaft 9 to drive the support leg 10. When the support leg 10 is extended, the elastic force provided by the buffer spring 14 is used to extend the extension sleeve 15, so that the extension leg 16 is extended, and the damping column 12, the buffer spring 14, and the extension sleeve 15 cooperate with each other to reduce the shock of the machine body 1. At the same time, the movement of the screw sleeve 6 can drive the positioning frame 18 to move. When the support leg 10 is extended, the positioning frame 18 is directly below the anti-deflection pad 20. At this time, the electric telescopic rod 19 is started to make the anti-deflection pad 20 contact the ground through the positioning frame 18, and the friction between it and the ground is used to prevent the machine body 1 from moving easily, thereby completing the positioning.
