Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As shown in Fig. 1 to Fig. 5, LCD processing platform angle rotational correction device of the present invention, comprise base plate 1, rotate stationary shaft 2, crossed roller bearing 3 and platform 4, the one end rotating stationary shaft 2 is arranged on base plate 1, crossed roller bearing 3 is sleeved on the other end of rotation stationary shaft 2, described platform 4 is arranged on crossed roller bearing 3, and platform 4 can rotate by opposed bottom 1; Also comprise and be arranged on the drive motor 5 between base plate 1 and platform 4, the leading screw 6 driven by drive motor 5, the slide rail 7 axially be arranged in parallel with leading screw 6, be arranged on slide rail 7 and can along the slide block 8 of slide rail 7 movement; Described slide block 8 is enclosed within leading screw 6, movable slider 8 can be with to move axially along leading screw 6 by the rotation of leading screw 6; Slide block 8 is also provided with Cam Follower 9, in the bottom surface of platform 4, Cam Follower 9 correspondence position is provided with the block 10 contacting with Cam Follower 9 and coordinate; Moved axially along leading screw 6 on slide rail 7 with slide block 8 by Cam Follower 9, block 10 can be promoted platform 4 is rotated around the axis of crossed roller bearing 3; Also comprise back-moving spring 11, one end of described back-moving spring 11 is fixedly connected with base plate 1, the other end of back-moving spring 11 is connected with platform 4, and the torque direction of the axis around crossed roller bearing 3 that torque direction and the Cam Follower 9 pairs of platforms 4 of the axis around crossed roller bearing 3 that the back-moving spring 11 pairs of platforms 4 produce produce is contrary.
Specific works process of the present invention is as follows: when needs drive platform 4 rotate clockwise carry out angle correction time, start drive motor 5, leading screw 6 is driven to rotate by drive motor 5, and then drive the slide block 8 be enclosed within leading screw 6 to make it move on slide rail 7, simultaneously by the Cam Follower be arranged on slide block 89 pairs of block 10 applied thrusts, the axis around crossed roller bearing 3 after making platform 4 overcome the elastic force of back-moving spring 11 rotates.In like manner, when needs drive platform 4 to rotate counterclockwise to carry out angle correction, only leading screw 6 need be driven to rotate by drive motor 5, Cam Follower 9 pairs of block 10 applied thrusts be reduced, drives platform 4 to rotate counterclockwise by the elastic force of back-moving spring 11 like this.The mounting means of back-moving spring 11, can as shown in FIG., be arranged on back-moving spring 11 on base plate 1 by a mounting blocks 14.
As can be seen from the above analysis, rotated in the present invention by the rectilinear motion band moving platform 4 of Cam Follower 9, therefore the rotational angle levelling thickness range reality of platform 4 is less in theory, usually be no more than ± 15 °, also Just because of this, larger ratio of gear can be realized, therefore can improve load capacity.
In addition, in order to improve the precision of adjustment, monitor anglec of rotation size, the present invention also can comprise control system and sensor 12 simultaneously, described sensor 12 to be arranged on base plate 1 and corresponding with slide block 8, described sensor 12 and drive motor 5 respectively with control system signal communication.Now, detected the position of slide block 8 by sensor 12 in real time, the real-time rotational angle size under the relatively a certain initial setting state of platform can be obtained, and then make the rectification of platform more accurate.And so-called described sensor 12 and drive motor 5 respectively with control system signal communication, specifically refer to sensor 12 and the data detected are passed to control system, and control system can drive drive motor 5 after processing according to the data of sensor 12.
In addition, in order to make one-piece construction compacter, as shown in the figure, described leading screw 6 and drive motor 5 are separately positioned on the both sides rotating stationary shaft 2 by the present invention further, and leading screw 6 and drive motor 5 are by synchrome conveying belt 13 transmission.Certainly, now for the mounting means of leading screw 6, can adopt as shown in the figure, install respectively by clutch shaft bearing seat group 15 and the second bearing seat group 16.
General, block 10 can make rectangular structure, simultaneously general block 10 is projected as rectangle in platform 4 bottom surface, and the axes intersect of the center line in this rectangle length direction and crossed roller bearing 3; And further can be vertical with the angular bisector of the maximum angle that block 10 rotary motion trace is formed by the motion track of Cam Follower 9; The benefit of such setting is the peak torque that the thrust that Cam Follower 9 pairs of blocks 10 can be made to apply can produce to platform.
In addition, consider that Cam Follower 9 is for rectilinear motion, and block 10 is for rotating, therefore, in order to ensure the contact relation of the two, generally described Cam Follower 9 and block 10 being set to linear contact lay coordinates; The face that also can Cam Follower 9 contact with block 10 is a face of cylinder, and the face that described block 10 contacts with Cam Follower 9 is a plane; By the contact of the face of cylinder and plane, the two stable relative movement in moving process can be ensured.
In addition, in order to improve the control to rotational angle, drive motor 5 can be set to servomotor.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
