Eccentric-bushing-type high accuracy positioning device for code spraying product check machine sprayers

Abstract

The invention discloses an eccentric-bushing-type high accuracy positioning device for code spraying product check machine sprayers. The eccentric-bushing-type high accuracy positioning device comprises a bearing plate and linear guide rails installed at the two sides of the bearing plate. The two sides of the bearing plate are connected to the linear guide rails at the two sides in a slideable mode through sliding blocks separately. The bearing plate is provided with a sprayer fine adjustment positioning mechanism. The sprayer fine adjustment positioning mechanism comprises an outer sleeve, an eccentric sleeve which is connected into the outer sleeve in sleeved and rotatable modes, and a rotating shaft which is arranged in an eccentric hole of the eccentric sleeve in a rotatable mode. The rotating shaft is driven by a rotating angle servo motor to rotate. The eccentric sleeve is driven by an eccentric servo motor to rotate. The lower end of the rotating shaft is fixedly connected to a sprayer mounting base. The eccentric-bushing-type high accuracy positioning device is easy to process and assemble, low in cost, good in applicability, capable of achieving accurate real-time automatic positioning of the sprayers, high in positioning precision, high in speed and easy to operate.

Description

technical field [0001] The invention relates to the technical field of a code-spraying product inspection machine, in particular to an eccentric sleeve-type high-precision positioning device for a spray head of a code-spraying product inspection machine. Background technique [0002] The nozzle of the inkjet quality inspection machine needs to be moved when the job is changed, and its working position must be re-determined. For special jobs, the position of the nozzle needs to be adjusted in real time during the printing process, while the traditional inkjet quality inspection Most machines use mechanical adjustment devices, which require manual adjustment of the position. This manual adjustment method has the following disadvantages: cumbersome operation, time-consuming and laborious, slow progress, and cannot be adjusted in real time. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the present invention aims to provide an eccentr...
