Description

Two-part CD grabbing structure

Technical field:

The utility model relates to a kind of two-part CD grabbing structure, particularly a kind of mechanical arm two-part CD grabbing structure for CD server.

Background technology:

CD server is that a kind of volume is little, can be configured in the large Capacity Optical storage device electric using on general desk.He integrates storage, have access to, imprinting, multiple functional archives storage equipment.CD server must be provided with CD casket, but the flexible size of pallet of the flexible size of the compact disk carrier of CD casket and CD-ROM drive differs, and their position is arranged before and after can only doing again, machine volume could be narrowed down to the best.But by the size of stretching out of compact disk carrier, while moving to pulldown device central point, the installation site of CD-ROM drive must after move, not so CD-ROM drive will be collided by walking mechanism.If the size of stretching out by CD ROM support tray arranges, the compact disk carrier of CD casket just can not be pulled out to the best central point of desirable dish.

Summary of the invention:

A kind of two-part CD grabbing structure that the utility model is invented in order to solve the problems of the technologies described above just.

The utility model is realized by following technological means just:

A two-part CD grabbing structure, comprises the mechanical arm of two-part, the movable head of mechanical arm front end for can off normal moving, and mechanical arm rear end is mechanical arm elevating mechanism; The described movable head end can off normal moving is equipped with pulldown device; The movable head can off normal moving can make pulldown device depart from.

Described pulldown device departs from scope for to depart from and to be no more than 6 degree along movable head moving direction.

Described mechanical arm front end is all connected with left and right push-pull mechanism with mechanical arm rear end; Described left and right push-pull mechanism includes side-to-side movement motor, side-to-side movement guide rail, mechanical arm.On mechanical arm, be provided with movable head; On described left and right push-pull mechanism, be also provided with projection, projection can following left motion guide rail touches the shifting block being arranged on movable head during motion; By contacting and the activity of separated control movable head off normal with shifting block, the distance of coming balance CD casket pallet pull-out location and CD ROM support tray to stretch out, obtains best unification, has avoided the collision of walking mechanism.

Described movable head includes a central shaft, is provided with return spring on central shaft.

On described mechanical arm rear end, be provided with the spacing bearing pin that restraint head rotates.

The feature that the utility model differs in order to adapt to the flexible size of pallet of three critical pieces in CD server, and can guarantee safe operation under instruction, meet again and simplify configuration and the parts of the equipment Bian standard component of trying one's best, reach and reduce manufacturing cost and use cost, principle that again can reduced volume, mechanical arm is designed to simple front and back two-part, utilize cam principle, by leading portion be designed to the to be shifted movable head of deflection, solve three pallets and stretched out the key issue that size differs, guaranteed device security stable operation.

Figure of description:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is another angle structural representation of the utility model.

The specific embodiment:

Shown in Fig. 1, Fig. 2:

A two-part CD grabbing structure, comprises the mechanical arm 12 of two-part, the movable head 2 of mechanical arm 12 front ends for can off normal moving, and mechanical arm 12 rear ends are mechanical arm elevating mechanism 8; Described movable head 2 ends that can off normal move are equipped with pulldown device 11; The movable head 2 can off normal moving can make pulldown device 11 can depart from 6 degree or 10mm scope.

Described mechanical arm front end is connected by left and right push-pull mechanism 7 with mechanical arm rear end; Described left and right push-pull mechanism includes side-to-side movement motor 9, side-to-side movement guide rail 6, is provided with movable head 2 in side-to-side movement mechanism; Described left and right push-pull mechanism is also provided with projection 1, and projection 1 can following left motion guide rail touches the shifting block 3 being arranged on movable head during 6 motion; By the off normal activity with shifting block 3 touch controls movable heads 2.

Described movable head 2 includes a central shaft 4, on central shaft 4, is provided with return spring.

On described mechanical arm rear end, be provided with the spacing bearing pin 5 that restraint head 2 rotates.

Specific works flow process is as follows:

Mechanical arm is designed to two sections, the movable head 2 of leading portion for can off normal moving, make pulldown device can be offset about 10mm, 10mm can shorten by stroke in the mechanism of push-and-pull compact disk carrier, the compact disk carrier 10 of CD-ROM drive just can be arranged by normal position like this, so just solved two kinds of contradictions that the flexible size of parts differs, the drawback of the normal operation of impact has just solved.The main member of its shift mechanism be mounted in can side-to-side movement push-pull mechanism on projection 1, what he installed in movable head along with push-pull mechanism position 6 that can side-to-side movement moves to sets ahead at 3 o'clock, and shifting block 3 is promoted, and makes movable head 2 offset rotation 6 degree to 354 degree, about 10mm, carries out disc accessible work.

Having solved the flexible size of two above-mentioned parts differs and affects after the contradiction of operation, also needing to meet the working size requirement of ejecting drawer pallet, is also the extended position of CD ROM support tray so the flexible center of ejecting drawer is designed on center 360 degree after mechanical arm movable head resets.When mechanical arm 12 movable head off normal 10mm, mechanical arm 12 moves down, and from compact disk carrier 10, take out after CD, then rise to certain position, the travelling backwards of side-to-side movement parts, the mechanism of drive push-and-pull compact disk carrier 10, pushes back compact disk carrier in CD casket.Now due to the travelling backwards of this push-pull mechanism 7, be arranged on projection 1 travelling backwards thereupon on push-pull mechanism 7, projection 1 is along with the travelling backwards of travel mechanism, depart from very soon with the shifting block 3 on movable head 2, when projection 1 and shifting block 3 depart from beginning, be arranged on the return spring on mechanical arm movable head 2 central shafts 4, do not needing under the condition of reaction force, change into immediately active force, rapidly movable head 2 is pushed back to former 360 fixing degree centers, mechanical arm 12 rises or declines, and CD is put into the pallet that ejects drawer or CD-ROM drive.The off normal center of former fixed center and off normal 10mm, both off normal shift lengths are subject to again the control of spacing bearing pin 5, so the size of displacement is accurately.Side-to-side movement is to be subject to software instruction, by side-to-side movement motor 9, drives side-to-side movement push-pull mechanism, carries out orderly motion on side-to-side movement guide rail 6.Therefore work as compact disk carrier, CD-ROM drive holder, after ejecting drawer holder position operation on demand putting in place separately, the pulldown device 11 on mechanical arm 12 also can synchronously arrive the position under instruction, then by the cooperation of the another parts of being correlated with, carries out orderly, safe access work under instruction.After instruction works when this time completes, all parts are all got back to again original position standby.The work of wait next instruction.

Be more than that a kind of embodiment of the present utility model is described in detail, this embodiment is to understand the utility model design for those skilled in the art, should not be construed as the restriction to the utility model design.
