Description

Technical Field

[0001] This invention relates to the field of electronic component inspection, specifically to a device for inspecting the surface of electronic components based on visual analysis. Background Technology

[0002] Electronic components are the basic units that make up electronic circuits. They are used to realize the transmission, processing, storage or control of signals. They can be divided into active components and passive components. Passive components can work without external power, such as resistors, capacitors and inductors. Active components rely on external power to realize signal amplification or switching functions, such as transistors, integrated circuits and diodes. They are widely used in computers, mobile phones, home appliances, automotive electronics, industrial equipment and other fields. They are the "basic cells" of modern electronic devices.

[0003] Surface defects in electronic components directly affect their performance and reliability. Common surface defects include scratches, stains, and oxidation. These defects can cause component malfunctions during operation and even lead to safety issues. Surface defect detection can promptly identify and repair these defects, ensuring stable operation of components even in extreme working environments. To facilitate batch testing of electronic components, existing testing equipment uses a telescopic rod to push the electronic components from the feeding seat to below an electric suction cup. The electric suction cup, in conjunction with a rotating rod, then transfers the adsorbed electronic components to a conveyor. The conveyor then sequentially transports the electronic components to below the inspection camera. Although this method enables continuous feeding of electronic components, the electric suction cup requires repeated gripping, moving, releasing, and resetting, making the feeding process complex and time-consuming, thus affecting feeding efficiency. Furthermore, the inertia generated by the telescopic rod pushing the electronic components can easily cause them to shift or tilt, making it difficult for the electric suction cup to neatly grip and place the electronic components onto the conveyor.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1-8 The illustrated vision-based electronic component surface inspection device includes a base 1 and a storage housing 2 fixedly mounted on top of the base 1. A positioning frame 3 is fixedly mounted on top of the base 1, a feeding tray 4 is located at the bottom of the positioning frame 3, and a loading cylinder 5 is located on top of the positioning frame 3. Multiple electronic components can be vertically stacked inside the loading cylinder 5. A first discharge port corresponding to the loading cylinder 5 is opened on top of the positioning frame 3, allowing the electronic components in the loading cylinder 5 to sequentially enter the feeding tray 4. A conveying device 6 located between the feeding tray 4 and the storage housing 2 is fixedly mounted on top of the base 1. A detection probe 29 is fixedly mounted on top of the positioning frame 3. The electronic components in the feeding tray 4 can sequentially enter the conveying device 6, which transports the electronic components to below the detection probe 29, allowing the detection probe 29 to perform visual inspection of the electronic components. The device also includes a feeding mechanism that smoothly conveys the electronic components from the feeding tray 4. The feeding mechanism is installed inside the feeding tray 4.

[0031] The feeding mechanism includes four centrally symmetrically fixed mounting brackets 7 installed inside the feeding tray 4. Two centrally symmetrically distributed L-shaped support plates 8 are slidably mounted on the inner side of each mounting bracket 7. A first elastic clamping plate 9 is fixedly mounted on the outer side of each L-shaped support plate 8. A rack plate 10 is fixedly mounted on the side of each L-shaped support plate 8 near the first elastic clamping plate 9. A positioning sleeve 11 is fixedly mounted on the inner side of each mounting bracket 7. A transmission gear 12 is rotatably mounted on the end of the positioning sleeve 11 near the rack plate 10. Both rack plates 10 mesh with the transmission gear 12. When the transmission gear 12 rotates, it can drive the two rack plates 10 to move in opposite directions, causing the two L-shaped support plates 8 to respectively drive the two first elastic clamping plates 9 to move closer or further apart. A insertion rod 1 is slidably mounted on the inner side of the positioning sleeve 11. 3. Two centrally symmetrically distributed spiral strips 14 are fixedly installed on the inner side of the positioning sleeve 11. A spiral groove that mates with the spiral strips 14 is opened on the outer side of the insertion rod 13, allowing the spiral groove on its outer side to move along the outer side of the spiral strips 14 when the insertion rod 13 moves, thus rotating the insertion rod 13 during its movement. A prismatic rod 15 is fixedly installed at one end of the insertion rod 13, and the prismatic rod 15 is slidably installed on the inner ring of the transmission gear 12. When the insertion rod 13 rotates, it can drive the transmission gear 12 to rotate through the prismatic rod 15, realizing the clamping and releasing of the electronic components by the two first elastic clamps 9. A spherical abutment 16 is rotatably installed at the end of the insertion rod 13 away from the prismatic rod 15. A positioning rod 17 is fixedly installed on the top of the device base 1, and the feeding tray 4 is rotatably installed... On the outside of the positioning rod 17, a plurality of centrally symmetrically distributed first springs 18 are fixedly installed between the spherical abutment 16 and the mounting bracket 7. An arcuate groove is provided on the outside of the positioning rod 17 for the spherical abutment 16 to slide within a limited position. When the feeding disc 4 rotates, it can drive the spherical abutment 16 to move along the outside of the positioning rod 17. When the spherical abutment 16 enters the arcuate groove, the rebound force of the first springs 18 causes the spherical abutment 16 to abut against the arcuate groove, and the spherical abutment 16 can then pull the insertion rod 13 to move. A base 19 is fixedly installed on the outside of the positioning rod 17. A second discharge port is provided at the bottom of the base 19, located directly above the conveying device 6. When the spherical abutment 16 moves away from the arcuate groove, it can re-contact the outside of the positioning rod 17. The two first elastic clamps 9 on the outer side of the rack 10 can release the electronic components, allowing them to fall from the second discharge port on the chassis 19 into the conveying device 6, thus realizing the transfer of the electronic components. As the feeding tray 4 rotates, the electronic components can move to the underside of the detection probe 29, allowing the detection probe 29 to perform surface detection on the electronic components, achieving continuous feeding of the electronic components. A sleeve 35 is fixedly installed on the outer side of the rack 10, and the sleeve 35 is slidably installed on the inner side of the mounting frame 7, improving the stability of the movement of the rack 10. A guide slide 36 is fixedly installed on the side of the spherical block 16 near the mounting frame 7, and the guide slide 36 is slidably installed on the outer side of the mounting frame 7, improving the stability of the movement of the spherical block 16 and providing a limit for the movement of the spherical block 16.To prevent excessive impact of the spherical abutment 16 on the arc groove on the positioning rod 17, a fixing frame 37 is fixedly installed on the top of the positioning frame 3. A gear motor 38 is fixedly installed on the outer side of the fixing frame 37. An annular toothed groove that mates with the gear motor 38 is opened on the outer side of the feeding disc 4, allowing the gear motor 38 to drive the feeding disc 4 to rotate intermittently through the annular toothed groove on the outer side of the feeding disc 4, thus realizing the rotation of the positions of the four mounting frames 7. Two symmetrically distributed pulleys 39 are fixedly installed on the top and bottom of the sleeve frame 25. A long groove for limiting the sliding of the pulleys 39 is opened on the inner side of the mounting frame 22, allowing the sleeve frame 25 to drive the pulleys 39 to move along the long groove of the mounting frame 22, facilitating the smooth movement of the sleeve frame 25.

[0032] Example 2: Please refer to Figures 3-6 This embodiment further explains Example 1. The pressing mechanism shown in the figure includes a U-shaped slide 20 fixedly installed on the end of the L-shaped support plate 8 away from the mounting frame 7. A slide plate 21 is slidably installed on the outer side of the U-shaped slide 20. When the L-shaped support plate 8 moves, the slide plate 21 can be driven to move synchronously through the U-shaped slide 20. Four centrally symmetrical mounting frames 22 are fixedly installed on the inner side of the feeding tray 4. The four mounting frames 22 are respectively located on the outer side of the four mounting frames 7. Slide rods 23 are fixedly installed on the top and bottom of the slide plate 21. An inclined slide frame 24 for limiting the sliding of the slide rods 23 is fixedly installed on the inner side of the mounting frame 22, so that when the slide plate 21 moves, it can drive the slide rods 23 to move along the inner side of the inclined slide frame 24, and the slide plate 21 can move... The slide 21 can move along the inner side of the U-shaped slide 20 to achieve tilting movement. A sleeve frame 25 is slidably installed between two adjacent slides 21. The sleeve frame 25 is slidably installed on the inner side of the mounting frame 22. When the two slides 21 move, they can drive the sleeve frame 25 to move towards the mounting frame 7. A second elastic clamping plate 26 is fixedly installed on the side of the sleeve frame 25 close to the mounting frame 7. A baffle 27 is fixedly installed on the inner side of the feeding tray 4, so that the sleeve frame 25 can push the electronic components onto the baffle 27 through the second elastic clamping plate 26. The two second elastic clamping plates 26 work together to achieve positioning and clamping of the electronic components and to correct the position of the electronic components, preventing skew and ensuring the accuracy of the visual inspection of the electronic components by the detection probe 29.

[0033] Example 3: Please refer to Figure 1 , Figure 2 and Figure 8This embodiment further illustrates other embodiments. The feeding mechanism shown in the figure includes a control host 28 fixedly installed on the top of the positioning frame 3, and a detection probe 29 installed on the bottom of the control host 28. The top of the positioning frame 3 has a through hole for installing the detection probe 29, so that the detection probe 29 can detect the electronic components directly below and transmit the detection data to the control host 28. A sliding cavity is formed on the inner side of the positioning rod 17, and a slider 30 is slidably installed on the inner side of the sliding cavity. A pressure block is fixedly installed on one side of the slider 30. 31. An electric telescopic rod 32 is fixedly installed on the top of the positioning rod 17. A push block 33 is fixedly installed on the bottom end of the electric telescopic rod 32. A groove for limiting the sliding of the push block 33 is opened on the top of the slider 30. A stop block 34 is fixedly installed on the inner side of the groove. The outer side of the stop block 34 contacts the bottom of the push block 33. Both the side of the stop block 34 and the push block 33 that are in contact are inclined surfaces. When the electric telescopic rod 32 pushes the push block 33, it can drive the push block 33 to move along the inclined surface of the stop block 34, so that the push block 33 can be pushed by the stop block 34. The sliding block 30 moves, which in turn drives the pressure block 31 to move synchronously. The pressure block 31 then pushes the spherical abutment 16 to move, causing the two first elastic clamps 9 to release the electronic components. Multiple equally spaced second springs 41 are fixedly installed between the inner sides of the sliding block 30 and the positioning rod 17 to facilitate the movement and reset of the sliding block 30. A discharge port is provided at the bottom of the chassis 19. The control host 28 is connected to the electric telescopic rod 32 via a cable box. When the control host 28 detects a defect in the electronic component through the detection probe 29, it can activate the electric... The telescopic rod 32 causes the two first elastic clamps 9 to release the electronic components, which can then be discharged downwards from the discharge port on the chassis 19. The side of the pressure block 31 away from the slider 30 has an arc-shaped structure, and the arc surface of the pressure block 31 corresponds to the inner side of the positioning rod 17, which facilitates the movement of the spherical abutment 16 along the outer side of the pressure block 31. A receiving box 40 is provided at the bottom of the device base 1, and the receiving box 40 is located directly below the discharge port of the chassis 19. Defective electronic components can enter the receiving box 40 through the discharge port for centralized processing.

[0034] Working principle: First, the operator installs the feeding cylinder 5 containing electronic components onto the positioning frame 3. The bottom electronic component contacts the top of the feeding tray 4. Then, the operator starts the gear motor 38, which drives the feeding tray 4 to rotate via the annular toothed groove on the outer side of the feeding tray 4. The feeding tray 4 drives the four mounting frames 7 to move synchronously, causing the mounting frames 7 to drive the insertion rod 13 to make a circular motion via the positioning sleeve 11. The spherical abutment 16 on the insertion rod 13 moves along the outer side of the positioning rod 17, causing the bottom electronic component of the feeding cylinder 5 to fall onto the outer side of the mounting frame 7 directly below. At this time, the gear motor 38 runs again, causing the mounting frame 7 to drive the L-shaped support plate 8 to move. The L-shaped support plate 8 pushes the electronic component along the chassis 19 via the first elastic clamp 9. As the top moves, the spherical abutment 16 slides into the arc groove on the positioning rod 17. Utilizing the rebound force of the first spring 18, the first spring 18 pushes the spherical abutment 16 against the arc groove of the positioning rod 17. The spherical abutment 16 pulls the insertion rod 13 along the inner side of the positioning sleeve 11, causing the spiral groove on the insertion rod 13 to move along the spiral strip 14 inside the positioning sleeve 11. The insertion rod 13 can then rotate, causing it to drive the transmission gear 12 to rotate via the prismatic rod 15. The transmission gear 12 drives the two rack plates 10 to move in opposite directions, causing the two L-shaped support plates 8 to respectively drive the two first elastic clamping plates 9 to move closer together. The two first elastic clamping plates 9 can then clamp the two sides of the electronic component. Simultaneously, the L-shaped support plates 8 are carried by the U-shaped carriage 20... The sliding plate 21 moves synchronously, causing the sliding rod 23 on the sliding plate 21 to move along the inner side of the inclined sliding frame 24. The sliding rod 23, in turn, causes the sliding plate 21 to move along the inner side of the U-shaped sliding frame 20, pushing the sleeve frame 25 to move along the inner side of the mounting frame 22. The second elastic clamping plate 26 on the mounting frame 22 abuts against the other side of the electronic component, bringing the electronic component into contact with the baffle 27, thus achieving centered clamping and positioning of the electronic component. At this time, another mounting bracket 7 moves below the feeding cylinder 5, causing the electronic component in the feeding cylinder 5 to fall onto the outer side of the mounting bracket 7. Thus, with the intermittent rotation of the feeding tray 4, continuous feeding of electronic components is achieved. When the electronic component moves below the detection probe 29, the detection probe 29 performs a surface inspection on the electronic component. If damage is found on the surface of the electronic component during inspection, the detection probe 29 transmits the information to the control host 28, causing the control host 28 to activate the electric telescopic rod 32 via the cable box. The electric telescopic rod 32 pushes the push block 33, causing the push block 33 to move along the inclined surface of the stop block 34. The push block 33 then pushes the slider 30 to move via the stop block 34. The slider 30 drives the pressure block 31 to move synchronously, causing the pressure block 31 to push the spherical abutment 16 to move. The spherical abutment 16 pushes the insertion rod 13 to reset, causing the transmission gear 12 to rotate in the opposite direction. The two first elastic clamps 9 and the second elastic clamps 26 can move away from the electronic component, releasing the electronic component. The electronic component can then enter the receiving box 40 through the discharge port on the chassis 19, realizing the detection and screening of the electronic component.As the feeding tray 4 rotates intermittently, qualified electronic components can move to the top of the second discharge port of the chassis 19. Simultaneously, the spherical abutment 16 moves from the arc groove on the positioning rod 17 to the outside of the positioning rod 17. Utilizing the distance difference between the outside of the positioning rod 17 and the arc groove, the spherical abutment 16 moves closer to the mounting frame 7. Consequently, the two first elastic clamps 9 and the second elastic clamps 26 move away from the electronic components, releasing them. The electronic components can then fall through the second discharge port onto the conveying device 6. Finally, the conveying device 6 sequentially transports the electronic components into the receiving box 2, allowing the receiving box 2 to collect the qualified electronic components, thus achieving stable detection and continuous feeding.
