Detailed Description
In order to make the technical solution in the present specification better understood by those skilled in the art, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present specification, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
As previously mentioned, existing cleaning of LTO tape is accomplished primarily manually. The operator needs to clean the dust on the surface of the LTO magnetic tape by using a brush, then clean the interior of the LTO magnetic tape, and finally wipe the outer surface of the magnetic tape box body by using a rag. It can be seen that the manual cleaning is not efficient and there is also a risk of damaging the magnetic medium when cleaning the inside of the LTO tape. For this reason, the present application aims at designing a more efficient and less vulnerable cleaning solution for LTO magnetic tape.
FIGS. 1 and 2 are schematic structural diagrams of an LTO tape cleaning apparatus according to an embodiment of the present invention, including: the magnetic tape guiding bracket 1, the machine box 2, the spring locking mechanism 3, the dust collection hole 4, the filter screen 5, the motor 6, the fixed bracket 7, the air outlet 8, the air outlet 9, the switching power supply 10, the fan blade 11, the gauze 12, the electromagnetic gripper 13, the dust sensor 14, the magnetic tape limiting chute 15, the photoelectric switch 16, the relay switch 17, the display 18 and the magnetic tape slot 19.
The tape guide bracket 1 can slide along the tape insertion direction corresponding to the tape slot 19, and is used for guiding the LTO tape to be inserted into the machine box 2 and pulled out from the machine box 2 through the tape slot 19. Alternatively, the slot cross section of the tape slot 19 may be provided with brushes to clean the LTO tape of external dust as it is inserted.
In this embodiment, the LTO tape is required to be inserted into the case 2 through the tape limit slot 15. The tape limiting chute 15 can prevent the LTO tape from moving along other directions in the inserting and pulling process, and plays a limiting role.
Specifically, the cross section of the tape guiding bracket 1 is T-shaped, and a first extension end 11 is assembled on the spring locking mechanism 3 and extends out of the case 2 through a through hole (not shown) in the case 2, and another second extension end 12 is used as a seat support for the ITO tape, and the extension direction of the second extension end 12, the extrusion direction of the second extension end 12 to the spring locking mechanism 3, and the tape insertion direction are consistent or nearly consistent.
In this embodiment, the photoelectric sensing area of the photoelectric switch 16 covers the notch of the tape limiting slot 15, so as to detect whether the ITO tape is inserted into the casing 2, and after detecting that the ITO tape is inserted into the casing 2, control the dust collection assembly to collect dust on the LTO stage.
Here, the casing 2 is divided into an upper chamber and a lower chamber, and the upper chamber and the lower chamber are communicated through the dust suction hole 4. The dust collection assembly is positioned in the lower cavity of the machine box 2 and consists of a motor 6, fan blades 11 arranged on a rotating head of the motor 6 and a fixing bracket 7 for fixing the motor 6 in the lower cavity. The photoelectric switch 16 controls the motor 6 to rotate the fan blade 11 to generate negative pressure in the lower chamber, so that the LTO tape in the upper chamber is sucked through the suction hole 4. The photoelectric switch 16 can also control the motor 6 to stop rotating after the LTO magnetic tape is pulled out of the machine box by photoelectric sensing, so as to end dust collection work.
In the dust collection process, the dust sensor 14 is used for detecting a dust concentration index value outside the LTO magnetic tape, and outputting a high-level signal to the relay switch 17 when detecting that the dust concentration index value is lower than a first preset threshold value, so as to start triggering the electromagnetic gripper 13 to stretch the gripper to open a magnetic strip gate of the LTO magnetic tape, and cleaning the inside of the LTO magnetic tape is achieved. Similarly, when the dust sensor 14 detects that the dust concentration index value is lower than a second preset threshold value (the second preset threshold value is smaller than the first preset threshold value), a low-level signal can be output to the relay switch 17 to control the electromagnetic gripper 13 to close the magnetic stripe gate of the LTO magnetic tape.
Further, the dust concentration index value detected by the dust sensor 14 may be displayed on the display 18 above the outside of the housing 2. The operator knows the progress of cleaning the LTO tape by the dust concentration index value displayed on the display 18. If it is determined that the purge is ended, the switching power supply 10 may be turned off to stop power to the LTO tape purge. The switching power supply 10 of the present embodiment can convert the commercial power into the direct current and supply the direct current to each of the electrical devices in the LTO tape cleaning apparatus.
In addition, the two sides of the dust collection hole 4 in the machine box 2 are also provided with a detachable gauze 12 and a filter screen 5 for collecting dust and avoiding the dust from drifting everywhere. The bottom air outlet 8 and the air exhaust net 9 of the lower chamber of the machine box 2 are used for exhausting the air in the box.
The LTO tape cleaning apparatus of this embodiment operates as follows:
the operator lifts the first extension 11 extending outside the case 2 to pull the tape guide holder 1 out of the tape slot 19. Then, the ITO tape is abutted against the second extension end 12 of the tape guide bracket 1, and the ITO tape is inserted into the machine box through the tape guide bracket 1 according to the guidance of the tape limit chute 15. During the insertion process of the tape guide bracket 1, the first extension end 11 is driven to press the spring locking mechanism 3, so that the spring locking mechanism 3 locks the tape guide bracket, and the displacement of the ITO tape in the machine box is limited.
Meanwhile, after the photoelectric switch 16 senses that the ITO magnetic tape is inserted into the combination, the motor 6 is started to rotate the fan blades 11 to remove dust from the outer part of the ITO magnetic tape in a first stage.
When the dust sensor 14 detects a drop in dust concentration to a constant value, this indicates that the LTO cartridge body has been optimally cleaned. At this time, the dust sensor 14 outputs a high-level signal to the relay switch 17, and the power supply triggers the electromagnetic gripper 13 to extend the gripper, opens the magnetic stripe gate of the LTO tape, and starts to perform the second stage dust removal in the LTO tape and in the vicinity of the magnetic stripe gate under the action of negative pressure.
When the dust sensor 14 detects that the dust concentration value falls to a lower constant value, the dust sensor 14 outputs a low-level signal to the relay switch 17, and power supply to the electromagnetic gripper 13 is stopped, so that the electromagnetic gripper 13 is restored to the initial position, and the magnetic stripe gate of the LTO tape is closed.
Finally, the operator turns off the switching power supply 10, presses the first extending end 11 extending out of the machine box 2 to press the spring locking mechanism 3 to unlock the tape guide bracket 1, and cancels the displacement limitation. The operator further lifts the first extension 11 extending outside the housing 2 to remove the tape guide holder 1 from the housing together with the ITO tape.
It can be seen that the apparatus of this embodiment is divided into two cleaning stages, the first stage being primarily to clean dust deposited on the exterior of the LTO tape. After the external dust is cleaned to a certain extent, the second stage is carried out, and a magnetic strip gate of the LTO magnetic tape is opened to clean the inside, so that the external dust is prevented from entering the inside of the LTO magnetic tape, and important parts such as a magnetic head, a photosensitive sensor and the like are prevented from being polluted. In addition, through the arrangement of control components such as a photoelectric switch, a gray level sensor and the like, the ITO magnetic tape is automatically cleaned, and the investment of a large amount of labor cost is saved. And in the cleaning operation process, the ITO magnetic tape is positioned in the relatively closed machine box, so that dust can not fly to the external environment to cause pollution. And the operator can know the cleaning progress in real time through the display to determine whether to end the operation. In practical application, the size of the whole device can be controlled within 20x10x40cm, so that the device is very light and easy to carry into a calculation room, and an operator can work after receiving electricity.
In addition, the embodiment of the invention also provides a cleaning method applied to the LTO tape cleaning device. FIG. 3 is a schematic flow chart of a cleaning method according to an embodiment of the present invention, including the following steps:
step S302, removing the tape guide bracket from the tape slot of the LTO tape cleaning device.
Step S304, the LTO magnetic tape is guided and inserted into a machine box of the LTO magnetic tape cleaning device based on the magnetic tape guiding support, so that after the photoelectric switch of the LTO magnetic tape cleaning device senses that the LTO magnetic tape is inserted into the machine box, the dust collection assembly is controlled to collect dust on the LTO magnetic tape, and when a dust sensor of the LTO magnetic tape cleaning device detects that the dust concentration index value is lower than a first preset threshold value, the electromagnetic gripper is controlled to open a magnetic stripe gate of the LTO magnetic tape.
Specifically, in step S304, the LTO tape is inserted into the box through the tape slot against the second extension end of the tape guide bracket, and drives the second extension end of the tape guide bracket to press the spring locking mechanism in the box during the insertion process, so that the spring locking mechanism locks the tape guide bracket.

In some cases, the actions or steps recited in the claims can be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results.
