Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to an electronic component appearance defect detection device and a detection method thereof. Background Art

[0002] The prior art discloses a device for detecting appearance defects on both sides of electronic components with application number CN201922409355.7. It is proposed that the current device for detecting appearance defects on both sides of electronic components mainly relies on manual inspection, which has high production cost and low inspection efficiency. When manual inspection is performed, a high misjudgment rate is prone to occur during long-term work. Therefore, efficient appearance defect detection is carried out by setting up modules such as conveyor belts.

[0003] The deficiency of the above-mentioned prior art is that the position of the camera module in the prior device is fixed, that is, the shooting direction and shooting angle of the camera module for the electronic components on the conveyor belt are fixed. During the appearance inspection process, the rigid shooting angle and direction will make it impossible to fully identify many parts of the appearance of the electronic components, and then the appearance defect inspection work cannot be completed with high quality.

[0004] At the same time, the camera module at a fixed position has very limited time and position for shooting electronic components moving with the conveyor belt, which will further affect the quality of appearance inspection. In addition, the camera module that cannot be adjusted and coordinated cannot meet the inspection needs of appearance defects due to close and detailed shooting of some areas of electronic components.

[0005] To this end, we propose an electronic component appearance defect detection device and a detection method thereof to solve the above problems. Summary of the invention

[0012] As another technical solution, a regulating structure is provided between the annular frame and the rotating ring, and the regulating structure includes a regulating ring, a protrusion group and a lifting frame. The regulating ring is fixedly connected to the annular frame, the protrusion group is fixedly connected to the inner wall of the regulating ring, a lifting port is provided on the rotating ring, and the lifting frame is slidably connected in the lifting port. The shooting module is arranged on the lifting frame, and a lifting groove is provided on one side wall of the lifting frame.

[0016] A detection method for an electronic component appearance defect detection device comprises the following steps:

[0017] S1. The output shaft of the driving motor controls the transmission roller to rotate, which in turn drives the conveyor belt to operate. The conveyor belt carries multiple placing tables to move. The shooting module performs shooting and transmits the captured image data to the image detection module. The image detection module performs information processing to complete the appearance defect detection of electronic components. The above are all existing technologies and no redundant description is given.

[0018] S2. After placing the electronic components on the placing table, the electronic components are moved to the shooting module along with the placing table and the running conveyor belt. During this process, the output shaft of the driving motor drives the gear member to rotate through the transmission of the pulley and the belt member, and the meshing transmission of the two bevel gears, and then drives the gear ring and the rotating ring to rotate through the meshing relationship. The shooting module on the rotating ring will rotate around the electronic components on the placing table. During the rotation process, the shooting module will shoot and record the three surfaces of the electronic components at different angles and directions;

[0019] S3. When the placing table carries the electronic components and moves, the interception block below will contact the telescopic block extending out of the telescopic slot, and then the annular frame will be driven to move as a whole through the telescopic block and the connecting frame, so that the shooting module on the rotating ring can keep moving horizontally synchronously with the electronic components while rotating, and the shooting module always aims at the electronic components for shooting. The reciprocating column and the reciprocating slot are connected in a sliding manner, so that the transmission work is not affected;

[0020] S4. When the annular frame structure moves synchronously with the electronic components to the limit position and is blocked and cannot move further, the telescopic block squeezes the telescopic spring under the force of the inclined surface and retracts into the telescopic groove. The telescopic block is separated from the intercepting block and is no longer subjected to thrust. The annular frame structure is reset by the elastic force of the reciprocating spring and is ready for the next round of work:

[0021] S5. When the rotating ring drives the camera module to rotate relative to the annular frame, the lifting frame connected to the camera module will be squeezed by the convex block group on the regulating ring and the elastic force of the lifting spring on the lifting block, and will lift and slide relative to the lifting port at the designated position. During this process, the camera module will approach the electronic components to take detailed photos and move away from the electronic components to take overall photos.

[0022] S6. When the placing table and the electronic components move to the end with the conveyor belt, the lifting cylinder hole in the grabbing and flipping parts controls the lifting of the U-shaped frame, the clamping cylinder controls the clamping claws to approach and complete the clamping of the electronic components, the flipping motor controls the clamping claws to drive the electronic components to complete the flipping, and then the reciprocating slide rail controls the movement of the clamped electronic components to complete the transfer of the electronic components from one conveyor belt to another. Since the two conveyor belts are arranged vertically, the moving direction of the transferred electronic components changes, and the appearance defect detection work of the other three surfaces can be completed with the flipping.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In the present invention, two conveying modules can complete the batch delivery of electronic components, and two shooting modules can cooperate with the grabbing and flipping components to smoothly complete the shooting and detection of the six-side appearance of the electronic components. At the same time, the driving component can control the rotation to drive the shooting module to rotate periodically around the conveyor belt, so that the shooting module can complete the shooting of electronic components in multiple angles and directions in a comprehensive manner, thereby enhancing the detection quality of appearance defects of electronic components;

[0025] 2. In the present invention, by setting the slide plate and the connecting frame, the placing table carrying the electronic components can drive the shooting module to move synchronously with the electronic components through the telescopic block and other structures, so that the electronic components in the movement process can also maintain a stable and aligned state to complete the shooting work, further enhancing the inspection quality of the electronic components;

[0026] 3. In the present invention, with the help of the protrusion group on the regulating ring and the lifting frame controlled by the lifting spring, the shooting module can be close to or away from the conveyor belt at the specified position, and then can approach or move away from the electronic components as needed to complete the shooting work, which effectively improves the shooting quality of the electronic components and enables the detection work to be better completed.

DETAILED DESCRIPTION

The annular frame 9 and the rotating ring 10 are both sleeved on the conveyor belt 7. The rotating ring 10 and the output shaft of the driving motor 5 are connected through a driving component.

[0041] The photographing module 2 on the rotating ring 10 will rotate around the electronic components on the placing table 8. During the rotation, the photographing module 2 will photograph and record the three surfaces of the electronic components at different angles and directions, so that the detection work can be completed based on more sufficient data, thereby enhancing the detection effect.

[0042] Reference Figure 1-Figure 3 The driving components include a ring gear 11, a gear member 12, two bevel gears 42, a belt member 13 and two pulleys 14. The ring gear 11 is fixedly connected to the rotating ring 10. A bracket 1 40 and two brackets 2 41 are provided on the base 1. The gear member 12 is rotatably connected to the bracket 1 40.

The two bevel gears 42 are meshed with each other, one of the bevel gears 42 is connected to the gear member 12, and the two pulleys 14 are respectively arranged on the other bevel gear 42 and the output shaft of the driving motor 5. The two ends of the two belt members 13 are arranged on the two pulleys 14.

[0043] After the electronic components are placed on the placing table 8, the electronic components are moved to the shooting module 2 along with the placing table 8 and the running conveyor belt 7. During this process, the output shaft of the driving motor 5 drives the gear member 12 to rotate through the transmission of the pulley 14 and the belt member 13, and the meshing transmission of the two bevel gears 42, and then drives the gear ring 11 and the rotating ring 10 to rotate through the meshing relationship, smoothly providing power to complete the rotation work;

[0044] Reference Figure 1-Figure 5 , also includes a slide plate 15 and a connecting frame 16, the slide plate 15 is slidably connected to the base 1, the bracket 40 and the annular frame 9 are fixedly connected to the slide plate 15, a reciprocating groove 17 is provided on one side wall of the gear member 12, a reciprocating column 18 is slidably connected in the reciprocating groove 17, the reciprocating column 18 and the reciprocating groove 17 are connected by a reciprocating spring 19, the other end of the reciprocating column 18 is fixedly connected to one of the bevel gears 42, both ends of the connecting frame 16 are fixedly connected to the annular frame 9, a telescopic groove 20 is provided on the upper end surface of the connecting frame 16, a telescopic block 21 is slidably connected in the telescopic groove 20, one end of the telescopic block 21 is an inclined structure, the telescopic block 21 and the telescopic groove 20 are connected by a telescopic spring 22, and interception blocks 23 are provided on the lower end surfaces of the plurality of placing tables 8, and the plurality of interception blocks 23 are matched with the telescopic blocks 21;

[0045] During the movement of the electronic components carried by the placing table 8, the intercepting block 23 below will contact the telescopic block 21 extending out of the telescopic slot 20, and then the annular frame 9 will be driven to move as a whole through the telescopic block 21 and the connecting frame 16, so that the shooting module 2 on the rotating ring 10 keeps moving horizontally synchronously with the electronic components while rotating, and the shooting module 2 is always aimed at the electronic components for shooting. This setting makes the shooting more stable, and the image data used for detection, analysis and comparison is more accurate, thereby making the detection work better completed. The cooperative sliding connection between the reciprocating column 18 and the reciprocating slot 17 does not affect the transmission work. When the structure of the annular frame 9 moves synchronously with the electronic components to the limit position and is blocked and cannot continue to move, the telescopic block 21 squeezes the telescopic spring 22 under the force of the inclined surface and retracts it into the telescopic slot 20. The telescopic block 21 is separated from the intercepting block 23 and is no longer subjected to the thrust. The structure of the annular frame 9 is reset by the elastic force of the reciprocating spring 19, ready for the next round of work, and the automatic reset does not affect the efficient processing capacity of the device.

A lifting block 30 is slidably connected in the lifting groove 28 through a lifting spring 29, and the lifting block 30 is fixedly connected to the inner wall of the lifting port 27;

[0047] When the rotating ring 10 drives the shooting module 2 to rotate relative to the annular frame 9, the lifting frame 26 connected to the shooting module 2 will be squeezed by the convex block group 25 on the regulating ring 24 and the elastic force of the lifting spring 29 on the lifting block 30, and will be lifted and slid relative to the lifting port 27 at the designated position.

During this process, the output shaft of the driving motor 5 drives the gear member 12 to rotate through the transmission of the pulley 14 and the belt member 13, and the meshing transmission of the two bevel gears 42, and then drives the gear ring 11 and the rotating ring 10 to rotate through the meshing relationship, smoothly providing power to complete the rotation work, and the shooting module 2 on the rotating ring 10 will rotate around the electronic components on the placing table 8 as the center. During the rotation process, the shooting module 2 will shoot and record the three surfaces of the electronic components at different angles and different directions, so that the detection work can be completed based on more sufficient data, thereby enhancing the detection effect;

The cooperative sliding connection of the reciprocating column 18 and the reciprocating slot 17 does not affect the transmission work. When the structure of the annular frame 9 moves to the limit position synchronously with the electronic components and is blocked and cannot continue to move, the telescopic block 21 squeezes the telescopic spring 22 under the force of the inclined surface and retracts it into the telescopic slot 20.

In this process, the shooting module 2 will approach the electronic components for detailed shooting and move away from the electronic components for overall shooting. The distance adjustment meets the staff's needs for detailed inspection of electronic components.

After the electronic components are placed on the placing table (8), the electronic components are moved to the shooting module (2) along with the placing table (8) and the running conveyor belt (7). During this process, the output shaft of the driving motor (5) drives the gear member (12) to rotate through the transmission of the pulley (14) and the belt member (13) and the meshing transmission of the two bevel gears (42), and then drives the gear ring (11) and the rotating ring (10) to rotate through the meshing relationship.

The telescopic block (21) is separated from the intercepting block (23) and is no longer subjected to the thrust. The ring frame (9) structure is reset by the elastic force of the reciprocating spring (19) and is ready for the next round of work: S5, when the rotating ring (10) drives the photographing module (2) to rotate relative to the annular frame (9), the lifting frame (26) connected to the photographing module (2) is squeezed by the convex block group (25) on the regulating ring (24) and the elastic force of the lifting spring (29) on the lifting block (30), and moves up and down relative to the lifting opening (27) at a designated position.
