The processing unit 70 can further include an embedded system or an application specific integrated circuit (ASIC) having embedded program instructions.


In at least one exemplary embodiment, when the installation member 50 acquires the fastening element 2 from the receiving members 40, the first sensing devices 411 and 421 corresponding to the receiving members 40 can detect the installation member 50 and provide detection to the processing unit 70. When the installation member 50 fastens the fastening element 2 to the electronic device 3, the second sensing devices 310 and 320 corresponding to the guiding holes 210 can detect the installation member 50 and provide detection to the processing unit 70.


In at least one exemplary embodiment, when the installation member 50 is detected by a specific one of the first sensing devices and a specific one of the second sensing devices, the processing unit 70 determines whether a specific one of the receiving members 40 corresponding to the specific first sensing device corresponds to a specific one of the guiding holes 210 corresponding to the specific second sensing device based on the corresponding relationship stored in the storage device 60.


In at least one exemplary embodiment, when the specific receiving member is determined to correspond to the specific guiding hole, the processing unit 70 can control the installation member 50 to fasten the fastening element 2. For example, the processing unit 70 can determine that the installation member 50 acquires a fastening element 2 from the first receiving member 41 and moves towards the first guiding hole 211 if the installation member 50 is sequentially detected by the first sensing device 411 and the second sensing device 310. Then, the processing unit 70 can determine that the position from which the fastening element 2 is acquired is the first receiving member 41 based on detection of the first sensing device 411 and that the position through the fastening element 2 will be fastened is the first guiding hole 211 based on detection of the second sensing device 310. Since the first receiving member 41 corresponding to the first sensing device 411 is determined to correspond to the first guiding hole 211 corresponding to the second sensing device 310 based on the corresponding relationships, the processing unit 70 controls the installation member 50 to fasten the fastening element 2 acquired from the first receiving member 41 to the electronic device 3 through the first guiding hole 211. In at least one exemplary embodiment, the processing unit 70 can look up the corresponding relationships to determine the relationship between the first receiving member 41 and the first guiding hole 211.


In at least one exemplary embodiment, when the specific receiving member is determined to not correspond to the specific guiding hole, the processing unit 70 can stop the installation member 50 from fastening the fastening element 2. For example, the installation member 50 is sequentially detected by the first sensing device 421 and the second sensing device 310. Since the second receiving member 42 corresponding to the first sensing device 421 is determined to not correspond to the first guiding hole 211 corresponding to the second sensing device 310, the processing unit 70 stops the installation member 50 from fastening the fastening element 2. Thus, the fastening element 2 acquired from the second receiving member 42 cannot be fastened to the electronic device 3 through the first guiding hole 211.


In at least one exemplary embodiment, when the installation member 50 is detected by a specific one of the first sensing devices, the processing unit 70 can control a specific one of the pilot devices corresponding to the specific first sensing device to provide a pilot signal. For example, when the installation member 50 is detected by the first sensing device 411 corresponding to the first receiving member 41, the processing unit 70 can control the first pilot device 311 corresponding to the first guiding hole 211 to provide the pilot signal. Thus, the fastening element 2 can be fastened to the electronic device 3 through the first guiding hole 211 based on the pilot signal provided from the first pilot device 311.


In at least one exemplary embodiment, the electronic device 3 can include a plurality of fastening holes (not shown). The fastening elements 2 are fastened into the fastening holes of the electronic device 3 through the guiding holes. After the fastening elements 2 are fastened into all of the fastening holes of the electronic device 3, the cover 20 can be uncovered so that the electronic device 3 can be removed from the fastening device 1. For example, the electronic device 3 includes four fastening holes. After the four fastening holes are fastened into the four fastening holes of the electronic device 3 through four guiding holes of the cover 20, the processing unit 70 can determines that the fastening process of the electronic device 3 ends. Thus, the cover can be uncovered and the electronic device 3 can be removed from the fastening device 1.


In at least one exemplary embodiment, the fastening device 1 further includes a base 80 as shown in FIG. 2. The base 80 includes a plurality of receiving parts 81, a shaft 82, a locking member 83, and a button 84. The receiving parts 81 can receive the plurality of receiving members 40. The mounting member 10 is mounted on an upper surface of the base 80. The cover 20 can rotate about the shaft 82 to cover the mounting member 10. The locking member 83 can lock the cover 20. The base 80 can supply power to the fastening device 1 by pressing the button 84 to turn on the fastening device 1.

In at least one exemplary embodiment, the second sensing devices can detect the installation member 50 when the installation member 50 moves towards the guiding holes with the acquired fastening element 2. If the installation member 50 moves towards the first guiding hole 211 with the acquired fastening element 2, the second sensing device 310 can detect the installation member 50. If the installation member 50 moves towards the second guiding hole 212 with the acquired fastening element 2, the second sensing device 320 can detect the installation member 50.


At block 93, the processing unit 70 determines whether the specific first sensing device corresponds to the specific second sensing device. If the specific first sensing device is determined to correspond to the specific second sensing device, the procedure goes to the block 94. If the specific first sensing device is determined to not correspond to the specific second sensing device, the procedure goes to the block 95.


In at least one exemplary embodiment, the first sensing device 411 corresponds to the first receiving member 41, and the second sensing device 310 corresponding to the first guiding hole 211. Thus, the first sensing device 411 is determined to correspond to the second sensing device 310 when the first receiving member 41 corresponds to the first guiding hole 211 based on the corresponding relationship stored in the storage device 60. In at least one exemplary embodiment, the first sensing device 421 corresponds to the second receiving member 42, and the second sensing device 320 corresponds to the second guiding hole 212. Thus, the first sensing device 421 is determined to correspond to the second sensing device 320 when the second receiving member 42 corresponds to the second guiding hole 212 based on the corresponding relationship stored in the storage device 60. In at least one exemplary embodiment, the processing unit 70 determines that the installation member 50 is detected by the first sensing device 411 and the second sensing device 310. Since the first receiving member 41 corresponding to the first sensing device 411 is determined to correspond to the first guiding hole 211 corresponding to the second sensing device 310 based on the corresponding relationship stored in the storage device 60, the processing unit 70 determines that the first sensing device 411 corresponds to the second sensing device 310. In at least one exemplary embodiment, the processing unit 70 determines that the installation member 50 is detected by the first sensing device 411 and the second sensing device 320. Since the first receiving member 41 corresponding to the first sensing device 411 is determined to not correspond to the second guiding hole 212 corresponding to the second sensing device 320 based on the corresponding relationship, the processing unit 70 determines that the first sensing device 411 is determined to not correspond to the second sensing device 320.


At block 94, the processing unit 70 controls the installation member 50 to fasten the acquired fastening member 2 to the electronic device 3 through the specific guiding hole.


In at least one exemplary embodiment, the fastening element 2 acquired from the specific receiving member corresponding to the specific first sensing device can be fastened through the specific guiding hole corresponding to the specific second sensing device when the specific first sensing device is determined to correspond to the specific second sensing device. For example, the installation member 50 acquires the fastening element 2 from the first receiving member 41, and then moves towards the first guiding hole 211 with the acquired fastening element 2. The processing unit 70 can control the installation member 50 to fasten the fastening member 2 acquired from the first receiving member 41 to the electronic device 3 through the first guiding hole 211 since the first receiving member 41 is determined to correspond to the first guiding hole 211.


At block 95, the processing unit 70 stops the installation member 50 from fastening the acquired fastening member 2 to the electronic device 3 through the specific guiding hole.


In at least one exemplary embodiment, the fastening element 2 acquired from the specific receiving member corresponding to the specific first sensing device cannot be fastened through the specific guiding hole corresponding to the specific second sensing device when the specific first sensing device is determined to not correspond to the specific second sensing device. For example, the installation member 50 acquires the fastening element 2 from the first receiving member 41, and then moves towards the second guiding hole 212 with the acquired fastening element 2. The processing unit 70 can stop the installation member 50 to prevent the fastening member 2 acquired from the first receiving member 41 from fastening to the electronic device 3 through second guiding hole 212 since the first receiving member 41 is determined to not correspond to the second guiding hole 212.
