This application relates generally to a system for dismantling various components of a hard drive and more particularly, to a system that will identify and extract selected components from hard drives and destroy the data containing portions of the hard drive.
Various types of data are stored on the hard drives of computers. Such data may include personal confidential information concerning individuals. This data may include their social security numbers, financial information, health information and private telephone numbers as examples. The hard drives are also used to store corporate information which may include proprietary information such as developing products, customer lists, and business plans. The government may store confidential information including highly classified information on the hard drives.
When it is desired to replace the computer, the data must be removed from the hard drive so that it cannot be misused by unscrupulous individuals. Merely erasing the data by using the computer commands is not sufficient as the data can be recaptured. This is true even if the hard drive is removed for upgrade purposes. However, even if the hard drive is removed, something must be done to destroy the data.
One way of ensuring that the data cannot be used or recovered from an unwanted hard drive is to completely destroy the hard drive. This has been accomplished in the past by completely shredding the entire hard drive. However, as the hard drive is encased in metal, the complete destruction involves the shredding of a relatively large volume of metal that requires a lot of energy.
Additionally, hard dives use rare earth elements in their construction. Rare earth elements include cerium (Ce), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), holmium (Ho), lanthanum (La), lutetium (Lu), neodymium (Nd), praseodymium (Pr), promethium (Pm), samarium (Sm), scandium (Sc), terbium (Tb), thulium (Tm), ytterbium (Yb) and yttrium (Y). It is becoming desirable to recycle such elements. The complete destruction of a hard drive does not readily permit the recapture of such elements.
It is thus desirable to have a process and apparatus for reclaiming the elements of the hard drive that contain the rare earth elements and then destroying the data containing portion of the drive.
An example of a hard drive data destroying device that does not destroy the entire hard drive is shown and described in U.S. Pat. No. 8,851,404 entitled Hard Drive Shredding Device, issued Oct. 7, 2014 by Clark et al., the disclosure of which is incorporated herein by reference in its entirety. Another example of such a hard drive data destroying device is shown in co-pending U.S. patent application Ser.

a are schematic top and side views of yet another alternative method of milling the hard drive;
In general, the system described herein can be used for dismantling and extracting various components of electronic media storage devices such as HDD, SSD, and HHD hard drives. The HDD (Hard Disc Drive) hard drive is essentially a metal platter with a magnetic coating. The coating stores the data. A read/write head on an arm accesses the data while the platters are spinning in a hard drive enclosure. In SSD (Solid State Drive) hard drives, instead of the magnetic coating on top of platters, the data is stored on NAND flash memory (information pods). The SSD drive has no moving parts. The HHD (Hybrid Hard Drive) hard drive is a hybrid incorporating the HDD and the SSD principles.
As outlined by the flowchart shown in
When the manufacturers' barcode on the hard drive 2 is successfully captured, the dismantling machine queries its barcode database, which consists of all hard drives, 3.5 inch and 2.5 inch HDDs, SSDs, and HHDs that are currently or were formerly available on the market. The system will also accommodate the integration of newly developed memory drives that are produced in the future. The system's barcode database will also interface with a visioning system comprised of a pictorial database cataloging specific components of the various types of drives, which will consist of: a) the manufacturer's barcode on the face cover 12 and top head of the drive; b) circuit boards 14 as well as the orientation of the rare earth metals, which consist of c) the voice-coil magnet 16 and d) the spindle motor “18. The orientation of the hard drive cover 12, circuit boards 14”, voice-coil magnets 16, and spindle motors 18 will also be accompanied with specific x, y, and z numerical coordinates with the visioning system to aid in their designated extraction procedure. Additional logistic information can be integrated into the system's database for the removal of other desired components. Based on the type of drive identified in the holding chassis, the program will convey specific dismantling coordinates to the CNC interface, which consist of several dismantling stages that start from the outside of the hard drive to the inside.
The present device includes an operating system that integrates the following; but it has the capacity to be configured into one integrated system or expanded to more than the four systems currently presented. Further, the algorithm of the present embodiment's operating system has the capacity to be integrated, in part or in total, into other manufacturers' systems that are currently being developed or developed in the future:
1). A barcode reader system that has a database of all the manufacturers' barcodes for all the 3.5 inch and 2.5 inch HDDs, SSDs, and HHDs that are currently or were formerly available in the market. The manufacturers' barcodes that are captured with the reader will help the overall system determine the specific type of hard drive placed in the holding chassis, either a 3.5 inch or 2.5 inch HDD, SSD, or HHD, which will be conveyed to the product visioning database and G-code or conversational programming database to aid in the selection of the appropriate dismantling sequence to perform on the respective drive. The barcode reading system will have the capacity to capture corporate asset tags placed on the hard drives and couple them with their corresponding manufactures' barcode. The barcode reading system will also have the capacity to read QR and Data Matrix Codes that are directly applied by the manufacturer or third-party source like a governmental agency, public/private corporation or organization. The information retrieved may consist of a link to the manufacturer's or supporting company's website. The code may also provide text content like the make and model of the respective drive's; specs on the drives' circuit board along with recovery instructions. When the QR and Data Matrix Codes of a HDD or HHD drive are scanned by the code reader 10 shown in
2). A product visioning system with a database comprised of all the 3.5 inch and 2.5 inch HDDs, SSDs, and HHDs that are currently or were formerly available in the market. Each hard drive in the database will have images of their targeted components primarily consisting of: a) the hard drive cover 12, mainly for added product recognition and product orientation within the milling chamber; b) circuit boards 14, c) voice-coil magnets 16, and d) spindle coil 18. The captured images will have corresponding numerical x, y, and z numerical coordinates to aid in the extraction of their targeted components. The product visioning database will also have the capacity to integrate images of other desired components to extract from the drive.
3). A G-code or conversational programming system with a database, of all the 3.5 inch and 2.5 inch HDDs, SSDs, and HHDs that are currently or were formerly available in the market, will house the pictorial images of the respective drives' configuration from their exterior to interior including the targeted components shown in
4). The present device also includes a database, which is comprised of a pictorial database of the rare earth metals and their corresponding x, y, and z numerical coordinates on all 3.5 inch and 2.5 inch HDDs and HHDs that are currently or formerly available on the market. The database has the capacity to integrate newly developed memory drives, containing rare earth metals that are produced in the future.
As shown in
The dismantling process will be conducted on both sides of the hard drive, at the same time, in the following stages:
Stage 1: Prior to processing hard drives, all external hardware like mounting clips as well as plastic and metal casing need to be removed. The hard drive 2 will be placed, on its edge, in the vertical holding chassis 4 having an open center and which is mounted to a loading table. There are two distinct holding chassis; one for 3.5 inch drives and the other for 2.5 inch drives. When the hard drive 2 is introduced to its appropriate holding chassis through the opening 13, it will automatically index into the milling chamber 8, along the hard drive transport rails 9 through the opening 13. Holding clamps 15 in the perimeter of the holding chassis 4 will secure the hard drive 2 in place during the dismantling process. Both the barcode scanner and visioning camera 10 will proceed to scan the drive. The present machine will also be able to process hard drives that have their covers removed and the information platters milled out. These particular hard drives will be identified by the manufacturer's barcode placed on the top edge of the hard drive.
Once the hard drive 2 has been identified, coordinates received from the system's databases will be transmitted to the system's CNC interface directing the speed, depth and positioning of the milling spindle to bore out specific fastening screws from the cover of the hard drive 2. On specific hard drives, a wedging mechanism will be inserted along the outer edge of the drive's cover to help break the adhesive seal (not shown). At the same time, the milling tool 14 over the backside of the hard drive will receive coordinates from the databases to bore out screws, which are holding the drive's circuit board in place.
Once both sides complete the removal of their respective screws, the vertical holding chassis 4 will index forward, along the hard drive transport rails 9, into the dismantling chamber 22 to allow the cover 12″ of the drive and the circuit board 14 to be removed using a pick and place mechanism 22 including a suction nozzle, and then releasing the components onto the system's conveyor belt 23 below the dismantling chamber 22. The conveyor belt 23 runs the full length of the dismantling and milling chambers to capture all the dismantled and falling parts. Then the conveyor belt transports the collected components, like circuit boards, down stream for further manual or automated processing to occur. The milling tool 20 used to bore out the screws attached to the cover of the hard drive can also be automatically exchanged for an edging tool, which cuts around the perimeter of the hard drive cover (not shown). The described embodiment can be adapted with cooling nozzles that emit air, CO2, LN2, or micro lubricants in the form of a mist on the drive or through holes in the milling tools for better performance and extended wear (not shown). The described dismantling system can also be programmed to recover other desired components inside the hard drive.
Stage 2: The vertical chassis 4 holding the drive 2 is indexed back into the milling chamber 8, along the hard drive transport rails 9, where logistic coordinates from the system's databases again direct the milling tool 20 over the front of the hard drive, to bore out specific screws that are holding the voice-coil magnets in place, while the milling tool 14 over the back of the hard drive will receive coordinates from the system's databases, to bore out the fastening screws that are holding the voice-coil magnet from the back. The procedure for removing the rear fastening screws, of the voice-coil magnet 16, can also be performed during Stage 1 when the circuit board is being removed, by boring out targeted holes through the circuit board where the rear fastening screws are located. The milling tool 20 will also be directed to bore out a hole in the rear assembly of 3.5 inch HDD and HHD spindle hubs, which will enable the platters to be released during the pick and place process.
When Stage 2 of the milling process is complete, the vertical hard drive holding chassis indexes forward, along the hard drive transport rails 9, to the dismantling chamber 22 to allow the pick and place mechanism 24 to retrieve the voice-coil magnets “16” from the hard drive with a suction nozzle. A clamping mechanism 25, or magnetic clamp, can also be integrated into the dismantling chamber 22, to provide a more aggressive method for retrieving the voice-coil magnets. Then the coupled voice-coil magnets 16 are dropped into a separate holding container 26 that prevent the magnets' magnetism from interacting with the other magnets that have been collected.
During the period in which the voice-coil magnets 16 are removed, the pick and place mechanism 24 also removes the information platters 26 from the hard drive casing using the suction nozzle of the pick and place mechanism 24. Referring to
As shown in
Once the cutting tools 38 and 40 complete the 180 degree cutting path around the platter hub 34, the movement of the cutting tools 38 and 40 is reversed and the cutting tools 38 and 40 are returned to their original position.
In operation, a hardware drive platter clamp 50 clamps, applies pressure to, the hub of the hard drive 32 and each cutting tool is rotated about its axis as indicated by the arrows (2). The milling tools 42, 44, 46 and 48 are spun about their individual axes and lowered toward the platter 26 in the direction of arrows 5 until the lower ends of the milling tools 4244, 46 and 48 pass the platters 36 in the hard drive 30. The milling tools 4244, 46 and 48 are then rotated around the axis of the hub 32 as indicated by the arrows 4 and at the same time, each milling tool 4244, 46 and 48 moves radially inward toward the hub 32 as indicated by the arrows 3 grinding the platters into small particles.
When the milling tools 4244, 46 and 48 reach the hub 33, the movement is reversed and the milling tools 4244, 46 and 48 are rotated about the hub back to their original position. At the same time the milling tools 4244, 46 and 48 are move radially outward as indicated by the arrows 7 into their outermost position. Simultaneously, the milling tools 4244, 46 and 48 are raised as indicated by the arrows 6 into their original position.
Unlike 3.5 inch HDD and HHD platters that are primarily made of ridged aluminum, the handling and destruction of 2.5 inch HDD and HHD information platters require more care because of their fragile composition consisting of glass coated ceramic disks. Their method of destruction as shown in
Another method that can be used to destroy 2.5 inch HDD and HHD platters 50 is the use of a modified lapidary flat lap grinding device 72 as shown in
The present embodiment can also utilize a small shredder or hammer mill 89 to destroy the 3.5 inch and 2.5 inch platters of the hard drives. The destruction method is carried out when the information platters are dismantled from the hard drive with the pick and place nozzle 24 on to the system's conveyor belt 23. Sensors are used to identify the 3.5 inch and 2.5 inch platters. Then the platters are segregated from the other recoverd sub-components; and directed to the shredder. Where the platters are reduced to particulated that are 2 mm or less. A vacuum system with a HEPA filter is used to safely collect the particulates.
Stage 3 in the overall process: The 3.5 inch aluminum hard drive casing is indexed back into the milling chamber 8 where the milling tool 20 is automatically exchanged with a hole cutting tool (not shown) which proceeds to bore out the spindle motor embedded in the base of the hard drive casing. The aluminum slug containing the spindle motor falls into the holding tray 90 below shown in
Because of the comprehensive dismantling sequences stored on the system's databases, the present embodiment has the ability to dismantle hard drives that have varying layers of assembly. The system's programming further allows the integration of additional coordinates for the removal of other desired components from the hard drive.
The described dismantling process can also be performed in a linear fashion where the hard drive is placed in the vertical holding chassis; and then advances forward through a series of dismantling chambers and pick and place stations without having to index back and forth between the dismantling chamber and the pick and place station.
The present system can also be configured to perform the dismantling process horizontally where the milling tool is positioned over the hard drive in the milling chamber. Then the system's hard drive holding chassis, that is also positioned horizontally, indexes the hard drive into the dismantling chamber, along the hard drive transportation rails 9 where the vacuum nozzle, of the pick and place mechanism, removes the desired components. After the targeted components are retrieved, and placed in their respective resepticals (as previously outlined). The hard drive leaves the system's holding chassis, and is indexed into the horizontal opening of the 180 degree hard drive holding chassis 92 as shown in
The described embodiment can also be performed in a semi-automated manner. The system's operator will reliy on the automated milling process, in the milling chamber, to bore/core out the fastening screws of the hard drives. Then bypass the automated collection of targeted compoments in the dismantling chamber by attaching the 180 degree holding chassis to the end of the milling chamber's hard drive transport rails. This will allow for the dismantled components to fall onto the conveyor belt below, transporting them downsream where the targeted components can be manually collected; and information bearing material can be destroyed using the prescribed destruction methods previously mentioned.
The dismantling machine will also have the option of being configured with an automated hard drive “magazine” loader to further expidite the process.
Although the present embodiment is described in various configurations, automated to semi-automated, for dismantling hard drives, the process can be further consolidated by combining the operatons of both the milling and the dismantling chambers into a single stage.
The dismantling machine's computer interface, linked by an Ethernet cable or wireless connection, will allow the present embodiment to be performed and monitored onsite or remotely requiring minimal or no human interface. The computer interface will also allow for programmatic updates to the system's databases.
The dismantling machine's operating system keeps track of the drives that are introduced to the system. When the destruction process is completed a Certificate of Destruction 96 such as shown in
Additional variables can be added to the Certificate like a running count of sub-components collected; their relative weights; and their value based on current commodity and non-commodity pricing along with other dismantling demographics for productivity reports. However, some of the previously stated variables may not be utilized based on where the company operating the dismantling machine is positioned in the products recovery continuum. The operating system will also allow for the contents of the Certificate to be included with the material retrieved QR and Data Matrix codes to be printed immediately or saved to a Word document or convert it to a PDF that can be stored for future use or delivered electronically to another computer, smartphone or tablet.
A vertical hybrid dismantling fixture 100, shown in
Hard drives are typically configured with the same outer dimensions, which allow for the collection of plotted points in a database, directing the milling units 102 where to core/bore out the fastening screws as well as holding fixtures. The first stage of the dismantling process consists of the front hybrid dismantling fixture aligning the six-unit hybrid milling fixture over the fastening screws around the perimeter of the hard drive cover. Once the perimeter screws have been cored/bored out, a single milling unit, but others can be directed, sweeps across the surface of the hard drive coring/boring out the fastening screws on the interior. The corresponding suction units 106, mounted on the frame 104 of the front fixture 100, are retracted until the milling process is complete. Then the milling units retract. At that time, the suction units 106 index toward the surface being milled applying tension pressure before activating the suction. A separation tool (not show) may be activated to help break the adhesive seal around the front cover of the hard drive. While simultaneously on the back of the hard drive, the vertical six-unit hybrid milling fixture is directed to core/bore out the fastening screws from targeted components listed in the hard drive dismantling system's operating system. Not all six milling units may be used, but are available to the G-code/conversational programming system to aid in the milling process. The milling and dismantling process will simultaneously continue on both the front and back of the hard drive, starting from the outside to the inside until the targeted components are removed from the hard drive chassis. The targeted components that are removed will be placed in their respective containers that were previously described or they can be collected on the conveyor belt for downstream manual sorting or automated processing; and the information bearing material can be destroyed using the prescribed destruction methods previously mentioned.
The recovered components from the vertical hard drive dismantling machine can either be directly placed in their respective holding containers, which were previously described or allowed to fall onto the conveyor belt below, transporting them downstream where the targeted components can be manually collected and information bearing material can be destroyed using the prescribed destruction methods previously mentioned.
The Hybrid Dismantling and Suction fixture is best adapted to the horizontal hard drive dismantling system. The hybrid fixture is positioned over the hard drive shortly after the barcode and visioning systems identify the type of drive, either 3.5 inch or 2.5 inch HDD, HHD or SSD, in the holding chassis. The milling units 102 are directed by the system's G-code database where to core/bore the fastening screws; and are positioned directly above the fastening screws. When the perimeter are processed a single milling unit 102 sweeps across the hard drive eliminating the remaining fastening screws. Then the suctioning units remove the detached components, placing them in their respective collection containers. The six-headed hybrid dismantling fixture, featured in this present embodiment, will be primarily utilized to expedite the removal of hard drive covers; but it is not limited to more or less of the milling and suctioning units to perform the task. The combined milling and suction units, of the hybrid dismantling and suction fixture, make the system highly compatible with the 180 degree holding chassis because it consolidates the functions of the milling and dismantling chambers into one unit. The automated collection of targeted components in the dismantling chamber can be bypassed by attaching the 180 degree holding chassis to the end of the milling chamber's hard drive transport rails. The recovered components from the hybrid holding fixture can either be directly placed in their respective holding containers or allowed to fall onto the conveyor belt below, transporting them downstream where the targeted components can be manually collected and information bearing material can be destroyed using the prescribed destruction methods previously mentioned.
The system can be adapted for the dismantling of cell phones, smartphones, tablets, and laptops, as well as flat panel televisions and monitors.
