Embodiment Construction

[0026] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. As described above, the present invention provides a HGA universal tray and its universal tray assembly, which can replace the five trays used in the traditional HGA manufacturing process to carry, clean and test the HGA of the hard disk drive. Therefore, pallet cost is reduced, manufacturing process is simplified and production efficiency is improved. A detailed description will be given below.

[0027] Such as figure 2 As shown, the universal tray assembly of the HGA of the present invention includes several universal trays with the same structure. In this embodiment, the universal pallet assembly includes two stacked universal pallets 100, 100'. The structure of the universal tray 100 will be described below. refer to image 3 , the universal tray 100 includes an outer frame 110 having at least two opposite sides, ...

Abstract

The invention discloses a magnetic head folded-piece combined general tray which comprises an outer frame, a first inner rod and a second inner rod, wherein the second inner rod is parallel to and separated from the first inner rod. The ends of the first inner rod and the second inner rod are connected with the opposite edges of the outer frame. A plurality of positioning supporting posts and a plurality of pairs of first projections are arranged at equal intervals on the first inner rod. The part between each pair of first projections of the first inner rod is sunk to form a gap below a magnetic head folded-piece combination. A plurality of second projections are arranged at equal intervals on the second inner rod to resist one edge of a baseplate. Five type of trays used in the traditional HGA (Head-Gimbal Assembly) manufacturing process can be replaced by the general tray, so that the loading / unloading operation of a HGA is reduced, i.e. unnecessary workstations and operating personnel are reduced. Therefore, the production efficiency is improved, and meanwhile, the manufacturing cost is also lowered. The invention simultaneously discloses a general tray combination.

Description

technical field [0001] The invention relates to a device for manufacturing a disk drive, and more particularly to a universal tray for magnetic head gimbal assembly and a universal tray assembly thereof. Background technique [0002] A disk drive is an information storage device that uses thin-film magnetic media to store data. A typical disk drive includes a head stack assembly (HSA), a disk mounted on a spindle motor and driven to rotate by the spindle motor, and a motor base for encapsulating the above components. The head actuator assembly includes one or more head gimbal assemblies (HGA, headgimbal assembly) with magnetic heads. The magnetic head flies on the surface of the disk at high speed, and the arm coil assembly (ACA, arm coil assembly) located in the fan tail space of the head drive arm assembly drives the magnetic head to radially position on the disk to read or read from the concentric data track on the disk. Write data to it. The arm coil combination is us...
