Description

Technical Field

[0001] The present invention relates to the technical field of industrial automation, and particularly to an identification printing device. Background Art

[0002] In industrial production, when coding workpieces such as cement test blocks and precast concrete components with strong dust adhesion on the surface and strong substrate color development inertia, the limitations of traditional processes have posed a major challenge to the full-process quality control. The core contradictions are concentrated in three dimensions: the failure of the color development mechanism, insufficient engineering environment resistance, and the lack of data closed-loop. It is urgent to achieve breakthroughs through the collaborative innovation of material modification, process adaptation, and intelligent verification.

[0003] The thermal effect of laser on the surface of cement matrix presents a color development paradox of "shallow carbonization - deep inertia": although high-power output can induce local carbonization to form black marks, the bonding force between the carbonized layer and the substrate is weak and is easily peeled off during handling and friction; at low power, the laser energy cannot penetrate the dense layer of the material, and the mark appears grayish-white and translucent, and the contrast almost disappears on the light-colored substrate, resulting in a sharp increase in the misjudgment rate of the code scanning device. In addition, the non-uniform distribution of aggregates further exacerbates the color development defects. In the coarse aggregate area, due to the difference in thermal conductivity, the "spot effect" is easily formed, destroying the geometric integrity of the two-dimensional code module.

[0004] The wetting-curing process of traditional ink on the surface of cement substrate faces double dilemmas: the porous structure and high surface energy of the substrate lead to insufficient ink penetration depth, forming the phenomenon of "floating ink", and the wear resistance of the mark drops sharply; while the fine particles in industrial dust physically adsorb with the ink solvent, accelerating the blockage of the nozzle micropores and increasing the frequency of equipment shutdown for maintenance. Even with UV curing technology, the adhesion of the cured film layer to the substrate is still limited by the weak chemical bonding characteristics of cement hydration products and is prone to interlayer peeling in a humid environment.

[0005] The existing coding process relies on manual operation, which is prone to missing codes and mis-codes, and has low efficiency. The lack of synchronous verification between the dynamic two-dimensional code and the production database leads to the mismatch of batch information and component entities, causing the risk of misusing components in the assembly link. In addition, the coding device lacks an adaptive adjustment function and cannot dynamically optimize the printing parameters according to the surface state of the substrate, further exacerbating the fluctuation of mark quality. Summary of the Invention

[0006] In view of the above situation, to overcome the defects of the prior art, the present invention provides an identification printing device, which effectively solves the problems of low color development contrast between laser printing and cement substrate, difficult code scanning due to blurred marks, easy dust blockage of inkjet nozzles, frequent equipment failures; poor mark durability, easy to fall off and fade during handling and storage, and lack of verification in the coding process, making it difficult to ensure the accuracy and readability of the mark.

[0040] The working process of the above components is specifically as follows: RFID identification - painting - jacking by the jacking device - positioning by the positioning device - laser coding - code scanning.

[0041] When in use: Place the target workpiece on the transmission device 2, including but not limited to conveying devices such as conveyor chains, conveyor belts and cylinders that can transport items.
