Description

Attachment and detachment device of test device for hard disk drive

The present invention relates to a test apparatus for a hard disk drive, and more particularly, to a detachable apparatus thereof.

In general, a hard disc driver (HDD) is a computer auxiliary memory device that combines a head disc assembly (HDA) made of mechanical components and a printed circuit board (PCB) made of circuit components. It is an auxiliary memory device. Such a hard disk drive is widely used as a secondary memory device of a computer system because the head of the hard disk floats on the rotating magnetic disk while maintaining a small gap to magnetically write / read the data so that a large amount of data can be accessed at high speed. do.

Such a hard disk drive is assembled and subjected to various tests when shipped.

The manufacturing process of a general hard disk drive will be briefly described. After the assembly process, the fully assembled hard disk is subjected to the servo light process, and then the servo light process, then the function test process, and the burn-in fixing are used to test the performance. Next, the product is shipped through a post process such as a final test process to confirm that the hard disk drive set that has passed the burn-in process is normally defected.

Referring to the manufacturing process of the hard disk drive in detail, the first assembly process is a process of assembling a head disk assembly, which is a mechanical part of the hard disk drive, in a clean room.

At this time, the basic test is performed for about 20 to 25 minutes in combination with a specific test system.

The burn-in process, which is the fourth step of the manufacturing process, takes the longest time (normally 8 hours to 16 hours) of the hard disk drive manufacturing process, and is performed by a self-program on the rack in the burn-in room without a separate test system. This burn-in process refers to a process of pre-finding the defects existing on the disk in order to allow the consumer to use the hard disk drive normally and preemptively avoiding the defects when the drive is used.

The final test process, which is a fifth step, is a process for checking whether the hard disk drive set passed in the burn-in process is normally defected. The defect processing state of each hard disk drive set is tested using a specific test system. It is possible to connect the hard disk drive 1: 1 to each personal computer according to the user's environment, and each personal computer connected to the host computer through the local area network tests the set according to the test program. Will output Thereafter, the host computer displays the state data input from each personal computer on the display device, so that the operator located on the line determines whether to pass the monitored state data. Finally, it is shipped as a finished product through the shipment inspection process, packaging and shipment process.

In order to allow the consumer to use the hard disk drive normally, the burn-in process has been passed through the detection of defects on the disk in advance and precautions to avoid defects when using the drive. Then, after passing the final test process to check whether the HDD set is normally defected, the main test information is read by reading the maintenance information of the HDD set passed in the final test process. Pass the final acceptance test process.

At this time, in the final test step, the test equipment is installed by mounting each hard disk on the test equipment, and the device for fixing the hard disk drive and the device is installed in the test device.

Referring to the detachable device of such a test device in detail as follows.

The detachable device of the present invention is roughly divided into a guider 10 provided with a support 13, a locking pin 31 sliding with the guider 10 in a sliding manner, and a compression coil spring 32 supporting the locking pin 31.

The guider 10 is installed to move linearly along the guide grooves 14 extending in the mounting direction, respectively on both inner sides thereof. One end of the guider 10 is bent at a right angle to the support 12 is coupled to the hinge 13 type, the support 12 is rotated about the hinge 13 axis. The other end 11 of the guider 10 is configured to be bent at a right angle to move together when the hard disk drive is mounted. In addition, a locking hole 15 is formed in the guider 10. The locking pin 31 corresponding to the locking hole 15 is provided in the pogo pin holder 22 and the 40 pin holder 24 directions.

At this time, since the locking pin 31 is supported by the compression coil spring 32, the locking pin 31 is in a compressed state or an extended state. In addition, the locking pins 31 are installed at positions facing each other. The locking pin 31 is cap-shaped, and the upper portion is curved for sliding surface contact movement with the guider 10.

The rack push rod 20 functions as in the prior art, and the pogo pin holder 22 or the 40 pin holder 24 is connected to the pogo pin and the 40 pin when a hard disk drive is mounted, and the holder connected to the pin is printed on the test apparatus. It is connected to the circuit board.

When the user pushes the hard disk drive in the direction of the arrow to mount it on the test apparatus, the hard disk drive is in contact with the guider 10, and one end surface of the hard disk drive is in contact with one end of the guider 10 and moves with the rack holder 20. Subsequently, when the hard disk drive is pushed, the pins of the hard disk drive and the holders 22 and 24 are connected. Then, the locking pin 31 is inserted into the locking hole 15 by the compression coil spring 32, and the pin 31 and the hole 15 are tightened. The hard disk drive is fixed.

At this time, the support 12 is rotatably fixed to the guider 10 is positioned to surround the hard disk drive while rotating inward at the moment when the 40 pin and the pogo pin of the hard disk drive is connected to the 40 pin holder 22 and the pogo pin holder 24 Do not let go. That is, it is first fixed by the support 12, and secondly by the coupling force of the locking pin 31 and the locking hole 15. At the moment when the hinge 13 axis of the support 12 is moved to the guide groove 14, the support 12 is forcibly subjected to the rotational force.
