Description

Technical Field

[0001] The present invention relates to the technical field of visual sorting, and in particular to a computer hard disk sorting device based on machine vision. Background Art

[0002] The assembly process of a computer hard drive involves multiple steps, including disk manufacturing, assembly, testing and final packaging.

[0003] Disk Manufacturing:

[0004] The magnetic disks inside a hard drive (often called platters or disks) are manufactured in a dust-free environment and are typically made of an aluminum or glass substrate and coated with a magnetic material.

[0005] Installing the hard disk:

[0006] Component preparation: The various components of the hard disk include platters, read / write heads (magnetic heads), motors, control circuit boards and casings, all of which will be inspected before assembly.

[0007] Install the platters: In a dust-free environment, multiple platters are mounted on a spindle. The spindle is driven by a motor that can quickly rotate the platters.

[0008] Install the read / write heads: Each platter will have one or more read / write heads, which are moved across the surface of the platter by an arm (commonly called a magnetic arm) to read and write data.

[0009] Connecting circuits: The control circuit board will connect to the read / write head and motor to control the operation of the hard drive.

[0010] After the disk is installed or before the hard drive is packaged, the hard drive will undergo multiple rounds of testing and sorting, which includes using machine vision technology to detect defects on the surface of the computer hard drive and sorting according to the test results. The reasons for computer hard drive surface defect detection are: (1) During the production process of the hard drive and serial interface, scratches, dents, dirt and other defects appear, which may affect the performance and life of the hard drive; (2) The read / write head of the hard drive needs to maintain a very small gap with the surface of the disk during operation. Surface defects may cause the read / write head to contact the disk, causing damage or data loss. Therefore, it is very important to ensure that the surfaces on both sides are smooth and free of defects.

[0011] The existing computer hard disk sorting device has a relatively simple structure and function. When the computer hard disk (serial interface, disk or magnetic head) of the product conveyor line is placed upside down or in an inconsistent orientation, it is impossible to automatically adjust the angle, position or orientation of the computer hard disk, thereby failing to collect or detect image data of the computer hard disk that is placed upside down or in an inconsistent orientation, and further failing to ensure the accuracy of sorting.

When the pressure ring 325 is disengaged from the pressure-bearing member 342, the second return spring 343 is used to drive the limit pin 341 to disengage from the limit hole 221.

[0060] Working principle: When the hard disk module 6 on the product conveyor line 8 is conveyed to the bottom of the first CCD vision module 23, the control module 7 first controls the longitudinal cylinder 14 to lower the mobile frame 21 by a certain distance. The first CCD vision module 23 is used to collect image data of the hard disk module 6 and upload the image data to the control module 7 for recognition and analysis. Fig.10When the disk 61 and the magnetic head 62 in the hard disk module 6 are located at the top, the control module 7 is used to analyze whether there are scratches on the surface of the disk 61 and the magnetic head 62 during the assembly process, and the second CCD vision module 43 is used to collect the image data of the serial interface 63 at one end of the hard disk module 6. Fig.11 and 12 When the position of the serial interface 63 does not correspond to the position of the second CCD vision module 43, the control module 7 is used to control the telescopic member 441 to move the clamping block 442 to fix the hard disk module 6, and control the electromagnet 331 to be powered off. After the electromagnet 331 loses the magnetic attraction to the magnetic ring 324 after the power is turned off, the elastic force of the first return spring 332 drives the adjustment part 33 to move along the driving rod 312 as a whole until the first transmission gear 322 contacts the end cover 314 and stops. At this time, the second transmission gear 323 is engaged with the meshing tooth 42, and the first transmission gear 322 is disengaged from the fixed toothed disc 22. The control module 7 is used to start the drive. The driving motor 311 controls the first transmission gear 322 and the second transmission gear 323 to rotate through the driving rod 312, the key bar 313 and the rotating tube 321. The rotating second transmission gear 323 controls the first rotating ring 41, the second CCD vision module 43 and the clamping part 44 to rotate through the meshing teeth 42 until the second CCD vision module 43 can obtain the image of the serial interface 63 and stops. Then the control module 7 controls the telescopic part 441 to move the clamping block 442 to clamp and fix the hard disk module 6. The control module 7 is used to analyze whether there are surface defects such as scratches or stains on the surface of the serial interface 63.

[0061] Reference Fig.13 and 14 When the disk 61 and the magnetic head 62 in the hard disk module 6 are located at the bottom, firstly, the second CCD vision module 43 is controlled to correspond to the position of the serial interface 63, and the clamping block 442 is controlled to fix the hard disk module 6, and the image data of the serial interface 63 is collected by the second CCD vision module 43, and then the control module 7 is used to control the longitudinal cylinder 14 to raise and reset the movable frame 21, and then the control module 7 is used to control the electromagnet 331 to be energized, and the electromagnet 331 after being energized is magnetically attached to the magnetic ring 324, at which time the second transmission gear 323 is disengaged from the meshing tooth 42, and the first transmission gear 322 is meshed with the fixed toothed disk 22, and then the driving motor 311 is used to control the first transmission gear 322 to rotate, and the rotating first transmission gear 322 controls the first rotating ring 41, the second rotating ring 51, and the hard disk module 6 to rotate 180 degrees with the rotating shaft 52 as the axis by means of transmission connection with the fixed toothed disk 22, and then the first CCD vision module 23 is used to collect the image data of the disk 61 and the magnetic head 62.

[0062] When the disk 61, the magnetic head 62 and the serial interface 63 are all qualified in the visual inspection, the control module 7 controls the telescopic member 441 to move the clamping block 442 to release the hard disk module 6, and then the control module 7 controls the longitudinal cylinder 14 to raise and reset the moving frame 21;

[0063] When one of the disk 61, the magnetic head 62 and the serial interface 63 fails the visual inspection, the control module 7 is used to control the horizontal moving frame 13 to move along the horizontal guide rail 12 to the position of the unqualified product conveying line 9, and the control module 7 is used to control the telescopic part 441 to move the clamping block 442 to release the hard disk module 6, thereby achieving the purpose of automatically sorting the hard disk module 6 according to the surface defects and automatically adjusting the position of the hard disk module 6 during the sorting process.

[0064] In summary, the present application utilizes the design of the driving assembly 3, the first rotating component 4 and the second rotating component 5 to cooperate with each other. On the one hand, the position of the second CCD vision module 43 can be adjusted according to the position of the serial interface 63. On the other hand, when the disk 61 and the magnetic head 62 in the hard disk module 6 are located at the bottom, the hard disk module 6 can be controlled to rotate 180 degrees with the shaft 52 as the axis, so that the first CCD vision module 23 and the second CCD vision module 43 can collect the image data of the disk 61, the magnetic head 62 and the serial interface 63. When performing surface defect detection on a computer hard disk, usually, the two sides of the hard disk (i.e., the two sides of the disk) are similar in detection standards, but there may also be some differences. These differences are mainly reflected in the following aspects:

[0065] Production process: The two sides of the hard disk may use different processes or materials during the production process, which may lead to slight differences in the testing standards.

[0066] Functional requirements: The two sides of a hard drive may have different functional requirements. For example, one side may be used primarily for data storage, while the other side may be used for read and write operations. Such functional differences affect the sensitivity and criteria for defects.

[0067] Taking into account the technical specifications of the product, when surface defect detection is required on both sides of the hard disk module 6, the present application can achieve the purpose of double-sided detection by controlling the hard disk module 6 to rotate 180 degrees with the rotating shaft 52 as the axis. The surface defects of the hard disk module 6 are analyzed according to the image data and the information on whether the product is qualified is output. The qualified conveying hard disk modules 6 remain on the product conveying line 8, and the unqualified conveying hard disk modules 6 are sorted and moved to the unqualified product conveying line 9. After visual inspection and sorting, the positions of the hard disk modules 6 on the product conveying line 8 and the unqualified product conveying line 9 are kept consistent, which is convenient for subsequent assembly processes. It has the characteristics of automatic sorting according to the surface defects of the hard disk module 6 and automatic adjustment of the position of the hard disk module 6 during the sorting process.
