Description

Technical Field

[0001] This disclosure relates to the field of hard disk repair technology, and in particular to a head removal and installation device. Background Technology

[0002] Computer hard drives, often simply called hard drives, frequently fail during everyday use. To retrieve the data stored on a failed hard drive, the fault must be repaired. This process is commonly known as data recovery.

[0003] The hard drive head uses an elastic cantilever as a support and is elastically assembled with the hard drive platter. This design allows the head to suspend itself a few micrometers above the platter due to the airflow generated during relative motion, achieving high-speed operation with minimal wear. The elastic cantilever supporting the head conforms to its operational characteristics, with its elastic range and deformation tolerance on the micrometer scale. If external force causes its deformation to exceed the limit, it will malfunction.

[0004] A hard disk drive (HDD) disassembly and assembly auxiliary device for removing and assembling read / write heads is provided, comprising: an involute plate mounted on a rotating shaft in a cantilevered manner; two involute plates axially spaced and located at the same central angle form an involute plate group; the axial distance between the two involute plates in the same involute plate group is greater than the thickness of the hard disk platter but less than the distance between the two read / write heads in a head group; the two involute plates in the same involute plate group can rotate synchronously with the rotating shaft; the involute plate is formed by setting the arc edge of a fan-shaped plate as an involute edge; rotating the rotating shaft allows a pair of involute plates in the involute plate group to gradually cut between the two read / write heads in a head group with their involute edges, so that the two read / write heads are synchronously lifted away from the surface of the hard disk platter.

[0005] This device has the following shortcomings:

[0006] 1. When two objects achieve the desired displacement through continuous friction, mutual grinding inevitably occurs. Grinding inevitably produces debris, which inevitably scatters on the surface of the hard disk platter. Although this debris is almost invisible to the naked eye, it can cause devastating damage to hard disk platters where the permissible defect size is on the nanometer scale.

[0007] 2. When two objects achieve the desired displacement through continuous friction, mutual grinding inevitably occurs. This is detrimental to the integrity and expected lifespan of the workpiece and tool in this process. Summary of the Invention

Detailed Implementation

[0057] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0058] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0060] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0061] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0062] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0063] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0064] Reference Figure 1 One embodiment of this specification provides a magnetic head removal and installation device, which includes: a magnetic head support structure 1, a position adjustment structure 2, and a base 3;

[0065] The position adjustment structure 2 is fixed on the base 3, and the base 3 is used to support the position adjustment structure 2.

[0066] The head support structure 1 is fixed to the outside of the position adjustment structure 2. The position adjustment structure 2 is used to drive the head support structure 1 to move along a preset direction under the action of external force. The preset direction is the direction perpendicular to the surface of the hard disk platter.

[0067] The magnetic head support structure 1 is used to support the magnetic head (the magnetic head to be disassembled or installed) to move along a preset direction.

[0068] Reference Figures 2-6 When removing the read / write head, the head removal and installation device provided in this application places the base 3 on the hard drive's base A1, and the head support structure 1 contacts the head arm A2. The user adjusts the position of the head support structure 2, causing the head support structure 1 to support the head arm A2 in a direction perpendicular to and away from the hard drive platter surface, thereby increasing the distance between the head A4 and the hard drive platter A3 to assist the user in removing the head. When installing the head, the head support structure 1 supports the head arm A2 in a direction perpendicular to and closer to the hard drive platter surface.

[0069] Based on the cooperation of the magnetic head support structure 1, position adjustment structure 2 and base 3 provided in this application, the magnetic head can be precisely adjusted during the assembly and disassembly process, while the magnetic head is not ground and no debris is generated.

[0070] Reference Figure 7 In one embodiment, the position adjustment structure 2 includes: a fixed frame 21, a moving system 22, and a transmission system;

[0071] The fixed frame 21 is fixed on the base 3, the transmission system is fixed on the fixed frame 21, and the moving system 22 is connected to the transmission system. Under the action of external force, the transmission system drives the moving system 22 to move along the preset direction.

[0072] The magnetic head support structure 1 is fixed to the moving system 22.

[0073] The fixed frame 21 works with the base 3 to position the moving system. The transmission system transmits external force to the moving system 22, which drives the head support structure 1 to move along a preset direction, thereby controlling the movement of the head support arm to move vertically away from or close to the surface of the hard disk platter.

[0074] Reference Figure 7 In one embodiment, the moving system 22 includes a first moving member 221 and a second moving member 222, which move in opposite directions under the transmission of the transmission system.

[0075] The head support structure 1 includes a first cantilever 11 and a second cantilever 12. The first cantilever 11 is fixed to the first moving member 221, and the second cantilever 12 is fixed to the second moving member 222. The first cantilever 11 and the second cantilever 12 are arranged vertically opposite each other. The first cantilever 11 and the second cantilever 12 are used to simultaneously support the head support arms located on both sides of the hard disk platter A3 to move along a preset direction.

[0076] Generally, a pair of head support arms A2 are provided on both sides of the hard disk platter A3, and a head A4 is installed on each head support arm A2. Therefore, the head support structure 1 provided by this head removal and installation device includes a first cantilever 11 and a second cantilever 12, which simultaneously support the head support arms located on both sides of the hard disk platter A3 to move in a preset direction.

[0077] Reference Figure 7 In one embodiment, the transmission system includes: a first transmission component 231, a second transmission component 232, a transmission shaft 233, and a handle 234;

[0078] The handle 234 is fixed to one end of the transmission shaft 233, and the other end of the transmission shaft 233 is connected to the second transmission assembly 232. The second transmission assembly 232 is connected to the second moving part 222 and the first transmission assembly 231. The first transmission assembly 231 is connected to the first moving part 221.

[0079] The transmission system provided in this embodiment transmits external power to the drive shaft 233 via the handle 234. The drive shaft 233 transmits power to the second transmission component 232, and the second transmission component 232 transmits power to the first transmission component 231. Simultaneously with the power transmission, the second transmission component 232 transmits power to the second moving member 222, causing the second moving member 222 to move the second cantilever 12. The first transmission component 231 transmits power to the first moving member 221, causing the first moving member 221 to move the first cantilever 11.

[0080] YY+221423P

[0081] Reference Figure 7 In one embodiment, the first transmission assembly 231 includes a first externally threaded tube 2311;

[0082] The fixing frame 21 includes: a fixing frame body 211, which can be a polygonal square tube;

[0083] The first external threaded tube 2311 is sleeved inside the fixed frame body 211;

[0084] The first moving part 221 is sleeved inside the fixed frame body 211. One end of the first moving part 221 is provided with a first internal threaded hole 2211, which is connected to the thread on the outer wall of the first external threaded tube 2311.

[0085] Based on the threaded connection between the first internal threaded hole 2211 and the first external threaded tube 2311, the rotation of the first external threaded tube 2311 drives the first moving part 221 to extend and retract within the fixed frame 21.

[0086] Reference Figure 7 In one embodiment, the first transmission assembly 231 further includes: a first end cap 2312, and a first thrust plate 2313 disposed at one end of the first external threaded tube 2311;

[0087] The fixing frame 21 also includes a fixing frame connecting part 212, which is disposed on one side of the fixing frame body 211;

[0088] The fixing bracket connecting part 212 is provided with a fixing bracket recessed round hole 2121, which cooperates with the first end cover 2312 to hold the first thrust plate 2313.

[0089] In this embodiment, the fixed frame 21 and the first external threaded tube 2311 are relatively fixed in position by the fixed frame 2121 cooperating with the first end cap 2312. At this time, the first external threaded tube 2311 is rotated and the first moving part 221 moves relative to the fixed frame 21.

[0090] In this embodiment, there is a motion deceleration effect when the helical motion is converted into linear motion. Therefore, the advantage of this embodiment is that it can achieve precise micro-motion control.

[0091] YY+221423P

[0092] For example, the first end cap 2312 is fixed to the outside of the fixing bracket connection part 212, and the first end cap 2312 and the fixing bracket connection part 212 can be fixed by welding, threading or gluing.

[0093] Reference Figure 7 , Figure 9 and Figure 10 In one embodiment, the second moving member 222 includes: a second moving member body 2221, which may be a polygonal square tube;

[0094] The second transmission assembly 232 includes a second externally threaded pipe 2321;

[0095] The second external threaded tube 2321 is sleeved inside the body 2221 of the second moving part;

[0096] A first pin 2322 is provided at one end of the second external threaded tube 2321;

[0097] The first end cap 2312 is provided with a second internal thread hole 2312A, which is connected to the thread on the outer wall of the second external thread tube 2321.

[0098] The inner wall of the first external threaded tube 2311 is provided with a first keyway 2314, and the first keyway 2314 is connected to the first pin 2322.

[0099] In this embodiment, based on the threaded engagement between the second internal threaded hole 2312A and the second external threaded tube 2321, the rotation of the second external threaded tube 2321 drives the second moving part 222 to move relative to the fixed frame 21; at the same time, the connection between the first keyway 2314 and the first pin 2322 realizes the synchronous rotation of the second external threaded tube 2321 and the first external threaded tube 2311, which can also be said to realize the transmission of power.

[0100] For example, the second external threaded tube 2321 is provided with a through hole (not shown), and the first pin 2322 is installed in the through hole. The first pin 2322 is a cylindrical pin.

[0101] In this embodiment, there is a motion deceleration effect when the helical motion is converted into linear motion. Therefore, the advantage of this embodiment is that it can achieve precise micro-motion control.

[0102] Specifically, the fixed frame 21 is fitted inside the body 2221 of the second movable component, and the second movable component 222 moves telescopically relative to the fixed frame 21.

[0103] YY+221423P

[0104] Reference Figures 7-8 In one embodiment, the second transmission assembly 232 further includes: a second end cap 2323, and a second thrust plate 2324 disposed at the other end of the second external threaded tube 2321;

[0105] The second moving part 222 further includes: a second moving part connecting part 2222, which is disposed on one side of the second moving part body 2221;

[0106] The second moving part connecting part 2222 is provided with a second recessed circular hole 2222A, which cooperates with the second end cover 2323 to hold the second thrust table 2324.

[0107] In this embodiment, the second moving part 222 and the second external threaded tube 2321 are relatively fixed in position by the second concave circular hole 2222A and the second end cover 2323 cooperating to clamp the second thrust plate 2324. At this time, the second moving part 222 moves telescopically relative to the fixed frame 21 when the second external threaded tube 2321 is rotated.

[0108] For example, the second end cap 2323 is fixed to the outside of the second moving part connecting portion 2222. The second end cap 2323 and the second moving part connecting portion 2222 can be fixed by welding, threading, or gluing.

[0109] Reference Figures 7-8 In one embodiment, one end of the drive shaft 233 is provided with a handle 234, and the other end is provided with a second pin 2331; the inner wall of the second external threaded tube 2321 is provided with a second keyway 2325, and the second keyway 2325 is connected to the second pin 2331;

[0110] The second end cap 2323 is provided with a third internal threaded hole 2323A, and the outer wall of the drive shaft 233 is provided with an external thread, which is connected to the third internal threaded hole 2323A.

[0111] In this embodiment, external power is transmitted to the drive shaft 233 via the handle 234. Based on the second keyway 2325 connected to the second pin 2331, the power of the drive shaft 233 is transmitted to the second external threaded tube 2321. Alternatively, the second external threaded tube 2321 can be said to rotate synchronously with the drive shaft 233.

[0112] Compared with existing hydraulic and pneumatic telescopic devices, the advantages of this embodiment are that the power source for driving the axial dimension change is singular, and the method of controlling the axial dimension change is simple. For example, the drive shaft 233 is provided with a through hole (not shown), and the second pin 2331 is installed in the through hole. The second pin 2331 is a cylindrical pin.

[0113] In one embodiment, the threads on the outer wall of the first external threaded pipe 2311, the threads on the outer wall of the second external threaded pipe 2321, and the threads on the outer wall of the drive shaft 233 have the same pitch.

[0114] In this example, the multi-stage telescopic mechanism (i.e., the transmission system) adopts a coaxial screw drive with equal pitch. Its advantage is that the movement of each stage is at the same speed, equal amount, simultaneous and in the same direction.

[0115] Reference Figure 7 In one embodiment, the base 3 includes two support legs 31, which are connected to the fixing frame 21.

[0116] Compared with existing technologies, the beneficial effects of this example are reflected in:

[0117] 1. The device in this example enables the application of force in only one direction to the workpiece (magnetic head);

[0118] 2. As described above, the device in this example achieves the effect of applying force to the workpiece without grinding;

[0119] 3. Based on the above, the device in this example achieves zero debris scattering during operation;

[0120] 4. The main body of the device in this example adopts a multi-stage telescopic mechanism. Compared with existing hydraulic and pneumatic telescopic devices, the beneficial effect of this example is that the power source for driving the axial dimension change is singular.

[0121] 5. Compared with existing hydraulic and pneumatic telescopic devices, the beneficial effect of this example is that the method of controlling axial dimension changes is simple;

[0122] 6. In this example, the multi-stage telescopic mechanism adopts a coaxial screw drive with equal pitch. When the helical motion is converted into linear motion, there is a motion deceleration effect. Therefore, the advantage of this example is that it can achieve precise micro-motion control.

[0123] 7. In this example, the multi-stage telescopic mechanism uses a coaxial screw drive with equal pitch, which has the advantages YY+221423P

[0124] It also lies in the fact that the motion at each level is constant in speed, magnitude, timing, and direction;

[0125] 8. In this example, the multi-stage telescopic mechanism adopts a coaxial screw drive with equal pitch. Its screw motion is equivalent to a multi-start thread, and the axial displacement at one end is superimposed at the same speed. Another advantage of this example is that it can achieve rapid telescopic motion.
