Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, the printing and stamping process of the present invention comprises the following steps:
and S1, printing a first reference edge 1 arranged along one side edge of the roll material and a second reference edge 2 arranged along the other side edge of the roll material in the length direction of the roll material.
The first reference edge 1 and the second reference edge 2 are two parallel straight lines, and the distance between the two reference edges and the edge is equal. The first reference edge 1 and the second reference edge 2 can be used as references for subsequent printing and stamping, and can also be used for detecting the deviation between products in two-time die cutting.
And S2, printing the stamping scanning point 3 on the roll material based on the printed first reference edge 1 and the second reference edge 2.
Wherein, the punch scanning point 3 can be a rectangular square. When die cutting is carried out twice, the punching scanning point 3 is respectively positioned at a first die cutting and punching position of the first die cutting and punching and a second die cutting and punching position of the second die cutting and punching. Thus, before die cutting and punching, the roller knife scans and detects the punching scanning point 3 firstly. Preferably, the first roller knife and the second roller knife for performing die cutting and punching scan the corresponding punching scanning points 3 in a CCD scanning manner.
And S3, printing the product printing point 4 on the roll material based on the printed first reference edge 1 and the second reference edge 2.
Wherein, the product printing point 4 is used as a reference point for subsequent product processing.
S4, printing a first check line 5 on the web based on the printed first reference edge 1 and the second reference edge 2.
Wherein, the first check line 5 is a rectangular detection block. At this time, when the detection is performed based on the detection block, the detection is performed through the deviation of the cross fit between the right-angle position of the detection block and the roller knife. The above-described deviation detection method may be performed by a human eye or a CCD scanning method.
S5, printing a second inspection line 6 on the web based on the printed first reference edge 1 and the second reference edge 2.
Wherein the second inspection line 6 is a printed line of a round hole and a waist-shaped hole. At the moment, when the printed lines of the round holes and the waist-shaped holes are detected, whether the printed lines of the round holes and the waist-shaped holes are reserved on a product or not is observed, and whether the punching of the coil stock deviates or not is detected.
And S6, stamping the coil stock based on the printed stamping scanning point 3, the first inspection line 5 and the second inspection line 6.
Wherein, according to the actual requirement, one mode, two modes or multiple modes can be set. In one embodiment, stamping the web includes performing a first die cut stamping and a second die cut stamping on the web. At this time, two-mold products were obtained. The offset between the two mould products can be detected by the first reference edge 1 and the second reference edge 2.
S7, the printed and punched product is quality-checked based on the second check line 6.
When the second check line 6 is a printed line of round holes and kidney-shaped holes. Specifically, when no printed line of the circular hole and the waist-shaped hole is left on the product, it indicates that the die cutting is not deviated, and the product surrounded by the printed lines of the circular hole and the waist-shaped hole is entirely punched out. When the printed lines of the round holes and the waist-shaped holes are left on the product, the die cutting is deviated, and the product surrounded by the printed lines of the round holes and the waist-shaped holes is not integrally punched.
And S8, when the stamping is found to be deviated by the quality detection, removing the printing on the roll material and reprinting.
In addition, in order to prevent that the coil stock from taking place the skew when walking the material, walking of coil stock is expected to fix a position through calorie material tool, calorie material tool includes: the coil winding device comprises a first fixed block 7 contacted with one side edge of a coil, a second fixed block 8 separated from the other side edge of the coil, a movable fixed block 9 contacted with the other side edge of the coil, and a spring 10 connecting the movable fixed block 9 and the second fixed block.
In summary, in the printing, overprinting and stamping process of the present invention, the reference edge is printed on the coil, and the stamping scanning point, the product printing point, the first inspection line and the second inspection line are printed on the basis of the printed reference edge, so that the stamping precision can be ensured according to the printed stamping scanning point and the first inspection line during stamping, and the quality of the product can be rapidly detected through the second inspection line.
