Problems solved by technology

Although it is theoretically possible to use a three-coordinate measuring instrument for this test, it is difficult to place the huge equipment in the purification workshop necessary for the assembly of inclined blocks, and these precise measuring equipment are expensive and complicated to operate and are not suitable for use in the production process. Operate on a product-by-product basis

Embodiment 1

[0017] Embodiment 1. A device for measuring the position of a detachable hard disk drive inclined block cleaning sheet, such as figure 1 As shown, it includes a test bench 1 for fixing the inclined block to be tested, a guide rail 2, a high-magnification magnifying lens 1 3, a high-magnification magnifying lens 2 4 and a display screen 5. The test bench 1 is provided with a through hole perpendicular to the surface, and the hole can be vacuumed to facilitate the fixing of the inclined block; the surface of the test bench 1 also has a concave hole matching the positioning protrusion on the bottom of the inclined block, which is convenient for the inclined block to fix. placement and positioning. (Through holes and recessed holes in figure 1 covered by the placed diagonal block A). The high-magnification magnifying lens 1 3 and the high-magnification magnifying lens 2 4 are fixed parallel to the surface of the test bench 1 and are perpendicular to each other (because the detec...

Embodiment 2

[0018] Embodiment two, utilize the measuring device in embodiment one to carry out the method for measuring the position of the detachable hard disk drive inclined block cleaning sheet, comprising the following steps:

[0019] 1) Vacuum the through hole on the test bench 1, align the positioning protrusion on the bottom surface of the inclined block A to be tested with the corresponding concave hole on the surface of the test bench and place it so that the bottom surface covers the through hole, and the suction force through the through hole will The inclined block is fixed. oblique block structure such as figure 2 As shown in (a) and (b), a pair of adjacent short sides b and long sides c perpendicular to each other of the cleaning sheet face the high magnification lens 1 3 and the high magnification lens 2 4 respectively.

[0020] 2) Use high-magnification magnification lens 1 and high-magnification magnification lens 2 to perform 50-fold optical imaging on the short side b...

Abstract

This invention discloses a position measurement method for tilted block cleaning sheets of a separable disk driver, which applies a mode of non-contact optical measurement to observe two adjacent side edges of the cleaning sheet and compares them with the preset standard line to judge the installed position of the cleaning sheet and to see if the installed height and the parallel degree against the base meet the requirement.

Description

【Technical field】 [0001] The invention relates to the production and assembly technology of parts of a detachable hard disk drive, in particular to a method and device for measuring the position of a slant block cleaning sheet of a detachable hard disk drive. 【Background technique】 [0002] The slant block is an important part of the hard disk. It provides the slide rail for the read-write head to enter and exit the disk, and provides a space to accommodate the head when it moves out of the disk, and protects the head. In the detachable hard disk technology, the slant block is divided into two parts, one part is located in the detachable hard disk drive, which provides the space for the magnetic head to accommodate and the slide rail for entering and exiting; Another section of the slide rail. Since the detachable hard disk has two independent parts, and the magnetic head needs to travel between these two parts, the original closed hard disk storage internal space cannot gu...
