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.
Board 1 comprises base 11 and is fixedly mounted on this base 11 and the supporting base 12 vertical with base 11.Positioning fixture 2 is fixedly mounted on the base 11, and it is provided with locating slot 21, and this locating slot 21 mates with the exterior contour of hard disk 8.Z axis rail 6 is installed on the supporting base 12, and slide unit 7 slidably is installed on this Z axis rail 6.Rotational power spare 4 is installed on the slide unit 7, and its output terminal is connected with mill depression bar 3, and transmission should be rotated around its axis by mill depression bar 3.Lifting power spare 5 transmission slide units 7 move up and down along Z axis rail 6.Mill depression bar 3 has three, these three mill depression bars 3 are all rotatable to be installed on the flat board 9, wherein the input end of a mill depression bar 3 is fixedlyed connected with the output terminal of rotational power spare 4, this mill depression bar is realized interlock by driving belt and other two mill depression bars, these three mill depression bars are corresponding with the film at each screw hole place on the hard disk respectively, and on the movement locus of each film when being positioned at corresponding mill depression bar 3 and moving along negative Z-direction.This mill depression bar 3 comprises bar portion 31 and is installed in mill pressure head 32 in this bar portion 31, this bar portion 31 is connected with the output terminal of rotational power spare 4, and a side of this bar portion 31 is provided with two bracing frames that keep at a certain distance away 35, mill pressure head 32 be installed in this bracing frame 35 and can be relatively this bracing frame 35 move up and down along Z-direction.Be arranged with elastic component 33 on the mill pressure head 32, the two ends of this elastic component 33 respectively with mill on the pressure head 32 flange 321 and the basal surface butt of a bracing frame 35, thereby when making mill depression bar 3 contact with film, the elastic force by this elastic component 33, and can play certain buffer action by this elastic component 33 to the suitable pressure of film maintenance.In addition, the bottom of this mill pressure head 32 is provided with elastic body 34, and this elastic body 34 is the rubber bodies of electrostatic prevention, and the surface that this elastic body 34 contacts with film is the plane.
