Embodiment 1

[0026] Such as figure 1 As shown, the present invention includes a longitudinal positioning mechanism 3 arranged before the impression cylinder 1 of the printing equipment, a transverse positioning mechanism 4 arranged at the impression roller 1, an analysis compensation mechanism 5 arranged after the plate cylinder 2 ; Also includes a visual recognition controller 6 connected to the lateral positioning mechanism 4, the analysis compensation mechanism 5, and the printing plate cylinder 2, respectively.

[0027] The invention realizes multiple positioning through the combination of mechanical positioning and automatic visual recognition positioning. The first positioning adopts a mechanical positioning method to achieve precise positioning in the vertical direction and preliminary positioning in the horizontal direction. The second positioning uses a high-definition visual recognition system to achieve precise positioning in the horizontal direction. With compensation and fine-...

Embodiment 2

[0029] The present invention includes a longitudinal positioning mechanism 3 arranged before the embossing cylinder 1 of the printing equipment, a transverse positioning mechanism 4 arranged at the embossing roller 1, an analysis compensation mechanism 5 arranged behind the printing plate cylinder 2; The visual recognition controller 6 connected with the lateral positioning mechanism 4, the analysis compensation mechanism 5, and the printing plate cylinder 2 respectively.

[0030] The invention realizes multiple positioning through the combination of mechanical positioning and automatic visual recognition positioning. The first positioning adopts a mechanical positioning method to achieve precise positioning in the vertical direction and preliminary positioning in the horizontal direction. The second positioning uses a high-definition visual recognition system to achieve precise positioning in the horizontal direction. With compensation and fine-tuning positioning, the position...

Embodiment 3

[0034] On the basis of Embodiment 1 or Embodiment 2, a registration positioning method includes the following steps:

[0035] 1) Mechanical positioning; 2) Visual recognition positioning; 3) Analysis compensation positioning.

[0036] The specific method of step 1) is: first adopt the longitudinal positioning mechanism 3 to carry out mechanical positioning, adjust the front stop gauge 31 of the longitudinal positioning, so that the longitudinal line of the printed sheet 7 printed with the identification mark 71 is in a vertical state with the printing plate cylinder 2; at the same time , adjust the lateral positioning side gauge 32, so that the lateral position of the printed sheet 7 is basically consistent with the position of the printing plate information 21 on the printing plate cylinder 2.

[0037] Through mechanical positioning, adjust the longitudinal positioning front gauge 31 and the lateral positioning side gauge 32, so that the longitudinal line of the printed sheet...

Abstract

The invention relates to the field of printing, in particular to a precise overprinting and locating device and a locating method thereof. According to the technical scheme, the precise overprinting and locating device comprises a longitudinal locating mechanism, a transverse locating mechanism and an analysis and compensation mechanism, wherein the longitudinal locating mechanism is arranged in front of a pressing roller of printing equipment, the transverse locating mechanism is arranged at the pressing roller, and the analysis and compensation mechanism is arranged behind a printing forme roller; and the precise overprinting and locating device further comprises a visual identity controller, wherein the visual identity controller is connected with the transverse locating mechanism, the analysis and compensation mechanism and the printing forme roller. By means of the precise overprinting and locating device and the locating method thereof, the problem that existing precise overprinting and locating technologies are low in precise overprinting precision is solved.

Description

technical field [0001] The invention relates to the printing field, in particular to a register positioning device and a positioning method thereof. Background technique [0002] The traditional printing and packaging production adopts multi-stage process paths such as printing, bronzing, indentation, embossing, die-cutting, and waste stripping. This method is now widely used by more than 95% of enterprises in China. Therefore, each process needs to be manually operated independently, resulting in a large consumption of personnel, and the independent completion of each process will add new waste products in addition to manual work, thereby greatly reducing the yield of the product. Therefore, the automation of printing and packaging machinery is a major problem facing many technical R&D personnel. Due to the high-quality attributes of printed products, it has bright and accurate printing colors and requires precise overprinting. The post-press process bronzing, embossing, i...
