Description

Technical Field

[0001] The present invention relates to the field of electronic component detection, and in particular to an electronic component surface detection device based on visual analysis. Background Art

[0002] Electronic components are the basic units that make up electronic circuits. They are used to realize signal transmission, processing, storage or control. They can be divided into active components and passive components. Passive components do not require external energy to work, such as resistors, capacitors, inductors, etc., while active components rely on external energy to achieve signal amplification or switching functions, such as transistors, integrated circuits, diodes, etc. They are widely used in computers, mobile phones, home appliances, automotive electronics, industrial equipment and other fields, and are the "basic cells" of modern electronic equipment.

[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 failures during operation and even pose safety issues. Surface defect detection can promptly detect and repair these defects, ensuring stable operation of components even in extreme operating environments. To facilitate batch testing of electronic components, existing testing equipment uses a telescopic rod to push the electronic components from a feeder to the bottom of a motorized suction cup. The electric suction cup then uses a rotating rod to transfer the adsorbed electronic components to a conveyor device, which then transports the electronic components sequentially to the bottom of the inspection camera. Although this allows for continuous feeding of electronic components, the electric suction cup requires repeated grasping, moving, releasing, and resetting. This complex loading process and long loading time affect feeding efficiency. In addition, the inertia generated by the telescopic rod can easily cause the electronic components to shift and skew, making it difficult for the electric suction cup to neatly grasp and place the electronic components on the conveyor device.

[0023] Example 2: Please refer to Figure 3-Figure 6 , this embodiment further explains Example 1. The pressing mechanism in the figure includes a U-shaped slide 20 fixedly mounted on the end of the L-shaped support plate 8 away from the mounting frame 7. A slide plate 21 is slidably mounted on the outer side of the U-shaped slide 20.

Four mounting frames 22 are fixedly mounted on the inner side of the feed tray 4 and are symmetrically distributed. The four mounting frames 22 are respectively located on the outer sides of the four mounting frames 7. The top and bottom of the slide plate 21 are fixedly mounted with a slide rod 23, and the inner side of the mounting frame 22 is fixedly mounted with an inclined slide frame 24 for limiting the sliding of the slide rod 23. When the slide plate 21 moves, it can drive the slide rod 23 to move along the inner side of the inclined slide frame 24, and the slide plate 21 can It can move along the inner side of the U-shaped slide 20 to realize the tilting movement of the slide plate 21.

[0024] Example 3: Please refer to Figure 1 、 Figure 2 and Figure 8, this embodiment further explains other embodiments. The discharge mechanism shown in the figure includes a control host 28 fixedly mounted on the top of the positioning frame 3, a detection probe 29 mounted on the bottom of the control host 28, and a through hole for mounting the detection probe 29 is provided on the top of the positioning frame 3, 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 provided on the inner side of the positioning rod 17, and a slider 30 is slidably mounted on the inner side of the sliding cavity.

An electric telescopic rod 32 is fixedly installed on the top of the positioning rod 17, and 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, and a stopper 34 is fixedly installed on the inner side of the groove. The outer side of the stopper 34 contacts the bottom of the push block 33, and the contact surface of the stopper 34 and the push block 33 are both inclined structures. When the electric telescopic rod 32 pushes the push block 33 to move, it can drive the push block 33 to move along the inclined surface of the stopper 34, so that the push block 33 passes through the stopper 34. The movable slider 30 moves, and the slider 30 can drive the pressure block 31 to move synchronously, so that the pressure block 31 pushes the spherical block 16 to move, so that the two first elastic clamps 9 loosen the electronic component. A plurality of second springs 41 with equal distances are fixedly installed between the slider 30 and the inner side of the positioning rod 17 to facilitate the movement and reset of the slider 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 through the cable box. When the control host 28 finds that there is a defect in the electronic component through the detection probe 29, it can be electrically The movable telescopic rod 32 causes the two first elastic clamps 9 to release the electronic components, and the electronic components can be discharged downward from the discharge port on the chassis 19. The side of the pressure block 31 away from the slider 30 is 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 spherical block 16 to move 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.

[0025] Working principle: First, the staff installs the loading barrel 5 containing electronic components on the positioning frame 3, and the lowest electronic component contacts the top of the feeding tray 4. Then, the staff starts the gear motor 38, so that the gear motor 38 drives the feeding tray 4 to rotate through the annular tooth groove on the outside of the feeding tray 4, and the feeding tray 4 drives the four mounting racks 7 to move synchronously, so that the mounting rack 7 drives the insertion rod 13 to make a circular motion through the positioning sleeve 11, and the spherical block 16 on the insertion rod 13 moves along the outside of the positioning rod 17, so that the lowest electronic component of the loading barrel 5 falls to the outside of the mounting rack 7 directly below. At this time, the gear motor 38 runs again, so that the mounting rack 7 drives the L-shaped support plate 8 to move, and the L-shaped support plate 8 pushes the electronic component along the chassis 19 through the first elastic clamping plate 9. The top moves, and at the same time, the spherical block 16 slides into the arc groove on the positioning rod 17, and the rebound force of the first spring 18 is used to push the spherical block 16 against the arc groove of the positioning rod 17. The spherical block 16 pulls the insertion rod 13 to move along the inner side of the positioning sleeve 11, so that the spiral groove on the insertion rod 13 moves along the spiral strip 14 inside the positioning sleeve 11, and the insertion rod 13 can be in a rotating state, so that the insertion rod 13 drives the transmission gear 12 to rotate through the prismatic rod 15, and the transmission gear 12 drives the two rack plates 10 to move in different directions, so that the two L-shaped support plates 8 respectively drive the two first elastic splints 9 close to each other, and the two first elastic splints 9 can clamp the two sides of the electronic component. At the same time, the L-shaped support plate 8 is brought by the U-shaped slide 20 The movable slide 21 moves synchronously, so that the slide bar 23 on the slide bar 21 moves along the inner side of the inclined slide frame 24, and the slide bar 23 can make the slide bar 21 move along the inner side of the U-shaped slide 20, so that the slide bar 21 pushes the sleeve frame 25 to move along the inner side of the mounting frame 22, and the second elastic clamping plate 26 on the mounting frame 22 presses against the other side of the electronic component, so that the electronic component contacts the baffle 27, thereby realizing the centering clamping positioning of the electronic component. At this time, the other mounting rack 7 moves to the bottom of the upper barrel 5, so that the electronic component in the upper barrel 5 falls to the outside of the mounting rack 7. Thus, with the intermittent rotation of the feed tray 4, the continuous feeding of the electronic components is realized. When the electronic component moves to the bottom of the detection probe 29, the detection probe 29 detects the surface of the electronic component. During the inspection, if damage is found on the surface of the electronic component, the detection probe 29 transmits the information to the control host 28, so that the control host 28 starts the electric telescopic rod 32 through the cable box. The electric telescopic rod 32 pushes the push block 33, so that the push block 33 moves along the inclined surface of the stop block 34. The push block 33 can push the slider 30 to move through the stop block 34. The slider 30 drives the pressure block 31 to move synchronously, so that the pressure block 31 pushes the spherical block 16 to move. The spherical block 16 can push the rod 13 to reset, so that the transmission gear 12 rotates in the opposite direction. The two first elastic splints 9 and the second elastic splint 26 can move away from the electronic components, loosening the electronic components. The electronic components can then enter the receiving box 40 through the discharge port on the chassis 19, thereby realizing the detection and screening of the electronic components.As the feeding tray 4 rotates intermittently, qualified electronic components can be moved to the top of the second discharge port of the chassis 19. At the same time, the spherical stop 16 moves from the arc groove on the positioning rod 17 to the outside of the positioning rod 17. The distance difference between the outside of the positioning rod 17 and the arc groove can be used to move the spherical stop 16 close to the mounting frame 7. As a result, the two first elastic clamps 9 and the second elastic clamps 26 are separated from the electronic components, loosening the electronic components. The electronic components can then pass through the second discharge port and fall onto the conveying device 6. Finally, the conveying device 6 sequentially conveys the electronic components into the storage chassis 2, allowing the storage chassis 2 to store the qualified electronic components, thereby achieving the effect of stable detection and continuous feeding.
