Abstract
The present invention relates to a film grinder which comprises a Z-axis guide rail, a sliding table, a rotating power member, a lifting power member and at least one grinding press rod, wherein the rotating power member is arranged on the sliding table, and the output end of the rotating power member is connected with the grinding press rod, and drives the grinding press rod to rotate; the sliding table is arranged on the Z-axis guide rail; the output end of the lifting power member is connected with the sliding table, and drives the sliding table to move along the Z-axis guide rail. Films are flat pressed by the grinding press rod through the rotating power member, and the films are tightly pressed by the grinding press rod through the lifting power member so a to simulate the operation of manually pressing the films by operators, improve the production efficiency, reduce the labor intensity of workers, guarantee the quality of products and effectively prevent dust from entering a hard disc.
Description
[technical field]
The present invention relates to the hard disk manufacturing field, especially about a kind of device that is used to compress hard disk screw hole place film.
[background technology]
In the manufacture process of hard disk, the parts that some hard disk inside are arranged, as magnetic patch, need in Clean room, install, and it is these parts are fastening by the cooperation of screw and screw hole, but because these screw holes have been communicated with the inside and the outside air of hard disk, dust enters hard disk inside in order to prevent to carry out the follow-up manufacturing process of hard disk, need stick film at the screw hole place.Existing film generally is to be attached on the harddisk surface by hand by the operator, and compress this film by hand, so that film can seal this screw hole closely, but there is following shortcoming in this mode: 1) adopt manual operations, reduce production efficiency, be unfavorable for the production in enormous quantities of hard disk; 2) quality is wayward, is difficult for making the smooth screw hole place that is attached to closely of film, makes dust enter hard disk inside and damage hard disk easily; 3) increased working strength of workers.
[summary of the invention]
The object of the present invention is to provide a kind of film grinder that can automatically the film at hard disk screw hole place be pressed on harddisk surface.
The object of the present invention is achieved like this: this film grinder comprises Z axis rail, slide unit, rotational power spare, lifting power spare and at least one mill depression bar, rotational power spare is installed on the slide unit, its output terminal is connected with the mill depression bar and this mill depression bar of transmission rotates, slide unit is installed on the vertical Z axis rail, and lifting power spare transmission slide unit moves along the Z axis rail.
Be provided with positioning fixture under the described mill depression bar, this positioning fixture is provided with the locating slot that is used to locate hard disk.
Described mill depression bar has two at least, and one of them mill depression bar is connected with the output terminal of rotational power spare, and this mill depression bar is by belt and other mill depression bar interlock.
Described mill depression bar comprises bar portion and mill pressure head, this bar portion one side is provided with bracing frame, and the mill pressure head is installed on this bracing frame and can it moves along Z-direction relatively, is arranged with elastic component on this mill pressure head, one end of this elastic component is connected on the flange of mill pressure head, and its other end is connected on the bracing frame.
The bottom of described mill pressure head is provided with the rubber bodies of electrostatic prevention.
Described rotational power spare is a brshless DC motor, and lifting power spare is a servomotor.
Described servomotor turn-screw rotates, and the lead screw transmission slide unit moves up and down along Z-direction.
Described Z axis rail is supported on the supporting base, and this supporting base is fixedlyed connected with a base and vertical this base.
Compared with prior art, the present invention has following advantage: make the mill depression bar flatten film by rotational power spare, make the mill depression bar compress film by lifting power spare, thereby simulated operator's manual moulding sheet operation, improve production efficiency, reduced working strength of workers, guaranteed the quality of product, can prevent effectively that dust from entering hard disk inside.

[embodiment]
See also Fig. 1 to Fig. 5, film grinder of the present invention comprises board 1, positioning fixture 2, mill depression bar 3, rotational power spare 4, lifting power spare 5, Z axis rail 6 and slide unit 7.Positioning fixture 2 is used to locate hard disk 8, mill depression bar 3 is used for the film at hard disk screw hole 81 places is flattened and compresses, rotational power spare 4 is used for transmission mill depression bar 3 and rotates, lifting power spare 5 is used for transmission mill depression bar 3 and moves up and down along Z-direction, and Z axis rail 6 be used to lead slide unit 7 moves up and down along Z-direction.
In the present embodiment, rotational power spare 4 is a brshless DC motor 4, lifting power spare 5 is a servomotor 5, Z axis rail 6 is a rotatable screw mandrel 6 that is supported on the supporting base 12, servomotor 5 drive lead screws 6 rotate, and the slide unit 7 that 6 transmissions of screw mandrel are installed on the screw mandrel 6 moves up and down along Z-direction.
The course of work of this film grinder is as follows: 1) hard disk 8 is put into positioning fixture 2; 2) start rotational power spare 4 and lifting power spare 5, make mill depression bar 3 limits rotate the negative Z-direction motion in edge; 3) rigidly connect in the process of touching film at mill depression bar 3, the rotating speed of mill depression bar 3 is very fast, is convenient to grind depression bar 3 film is flattened; 4) lifting power spare 5 transmission slide units 7 and mill depression bar 3 continue to descend along negative Z-direction, and the rotating speed of rotational power spare 4 slows down, and the rotating speed of mill depression bar 3 also slows down thereupon, make mill depression bar 3 film can be pressed in closely the surface of hard disk 8.
Among the present invention, make the mill depression bar flatten film, make the mill depression bar compress film, thereby simulated operator's manual moulding sheet operation, improved production efficiency, reduced working strength of workers, guaranteed the quality of product by lifting power spare by rotational power spare.
