A device that precisely controls the rotation angle of the clamping part

Abstract

The present invention discloses a device of accurately controlling a rotation angle of a clamping part and a realization method thereof which mainly solve the problem in the prior art that the shake generated when a bottle is clamped causes a liquid in the bottle to generate bubbles, so that the later lamp detection is interfered. The device of accurately controlling the rotation angle of the clamping part comprises a clamping part, a servo motor, a servo driver and a programmable controller. A rotating shaft of the servo motor is connected with the clamping part, the signal output end of the servo motor is connected with the signal input end of the programmable controller, the driving signal input end of the servo motor is connected with the signal output end of the servo driver, and the signal input end of the servo driver is connected with the control signal output end of the programmable controller. By the above scheme, and according to the present invention, the purpose that the shake generated when the bottle is clamped is reduced, thereby avoiding the liquid in the bottle to generate bubbles to interfere the later lamp detection, is achieved, and the very high practical value and popularization value are realized.

Description

technical field [0001] The invention relates to a device for controlling the rotation angle of a component, in particular to a device for precisely controlling the rotation angle of a clamping part. Background technique [0002] The device for controlling the rotation angle of the clamping part includes a clamping part, a turntable, a star wheel for entering bottles, a support frame and a star wheel for releasing bottles. The turntable is evenly provided with a plurality of installation holes, and the installation holes are evenly distributed on the outer edge of the turntable. The components are set in the installation hole, and both ends of them are rotatably connected with the inner wall of the installation hole. The bottle inlet star wheel and the bottle outlet star wheel are respectively arranged on both sides of the support frame. The bottle inlet star wheel and the bottle outlet star wheel are evenly equipped with The size of the opening is the same as that of the ins...

AI Technical Summary

Problems solved by technology

[0003] The prior art has the following defects: after the phases of the bottle-in star wheel and the bottle-out star wheel and the turntable are compensated in the above scheme, the bottle is not in the middle of the clamping part when the bottle is clamped by the clamping part, and then the bottle is not in the middle of the clamping part when the bottle is clamped. The bottle will vibrate for a moment, causing bubbles to appear in the liquid in the bottle, which will interfere with the subsequent light inspection.
