and the pushing device 5 is arranged on the other side of the code printing platform 2, and is used for pushing a workpiece (a cam shaft) on the code printing platform 2 to the code printing component 3 side.

The controller, the mechanical arm, the laser controller 311, the lifting device 32, the pushing device 5 and the code reading device 4 are all connected with the controller.

The principle of the utility model lies in:

a plurality of workpieces (camshafts of heavy trucks) are sequentially transported to the marking platform 2 by the robot. The workpiece (camshaft) is conveyed to the marking platform 2, the pushing device 5 arranged on one side draws the workpiece (camshaft) towards the marking assembly 3, the end face of the placed workpiece (camshaft) is marked by the laser marking machine 31 in a laser mode, the pushing device 5 enables the workpiece (camshaft) to be close to the focus of the laser marking machine 31, and therefore the marking position of the workpiece (camshaft) is accurate; and after marking is finished, the marking content is verified through the code reading device 4. The automatic feeding of the workpiece (camshaft) is realized, the production efficiency is improved, the production labor cost is reduced, and the end face of the workpiece (camshaft) can be marked after the feeding is finished;

in order to enable the ready-to-reach-completion to be checked quickly, the code-reading device 4 is now fixed on the laser marking machine 31; and enables the code reading device 4 to detect the contents of the marking by the laser marking machine 31.

In this embodiment, as shown in fig. 4, the lifting device 32 includes a column 321, a driving device, and a slider 322; the driving device drives the sliding block 322 to move up and down on the upright post 321 (i.e. move up and down along the upright post 321); specifically, the driving device is a driving motor or a hand wheel, so that the lead screw rotates; the screw rod is arranged on the upright post 321 and arranged along the axial direction of the upright post 321; two slide rails are arranged on the upright post 321 along two sides of the screw rod, and the two slide rails are respectively matched with the bulges on two sides of the slide block 322; when the drive motor or hand wheel is rotated, the lead screw is rotated, thereby causing the slider 322, which is slidably connected to the lead screw, to move up and down. Thereby driving the laser marking machine 31 to move up and down. Because can place work piece (camshaft) of different sizes on beating sign indicating number platform 2 to mark the center of content at work piece (camshaft) as the example, when placing work piece (camshaft) that the diameter is great, the center of work piece (camshaft) obviously can become high, therefore the lift of laser lift 31 can adapt to this kind of altitude variation to accord with the mark demand of beating of work piece (camshaft) of different sizes.

In order to avoid the toxic gas and dust generated in the processing from floating in the air and influencing the health of workers; as shown in fig. 3, the code printing assembly 3 and the pushing device 5 are both located in a protective cover 21, and the protective cover 21 is connected with a smoke processor 22; when the laser marking machine 31 marks a mark and generates smoke, the smoke processor 22 operates, so that the smoke and the like are sucked into the smoke processor 22.

In order to facilitate the pushing device 5 to push the workpiece (camshaft) to the coding assembly 3, the pushing device 5 is a pneumatic or electric device; the push rod pushes the workpiece (camshaft) to the coding assembly 3 in a pneumatic or electric mode; since the position where the workpiece (camshaft) is placed is far from the position of the laser marker 31, it can be pushed by the pushing device 5 so that the workpiece (camshaft) approaches the focal point of the laser marker 31.

In order to facilitate the staff to check the contents to be marked, the front side of the marking platform 2 is further provided with a display screen 52, so that the staff can check the corresponding marking contents in real time.

In order to input or modify the marking content, a keyboard and a mouse may be disposed on the front side of the marking platform 2, so as to input the marking content to the controller through the input device 51. Modifications and re-entries may be made in real time as the display screen 52 finds the marking content to be unsatisfactory.

Embodiment two is an embodiment of a crankshaft for transporting a heavy truck:

the structure of the code printing platform 2, the code printing component 3, the code reading device 4 and the pushing device 5 is consistent with that of the camshaft embodiment; in the embodiment, the positions needing marking are different due to different specifications of the crankshafts; therefore, the laser marking machine 31 is required to be capable of moving in the direction perpendicular to the conveyor belt 1 and adjusting the pitch angle; therefore, the laser marker 31 is slidably provided on the translation device 6, and the translation device 6 is slidably provided on the lifting device 32 via the angle adjuster 7. So that the translation device 6 drives the laser marking machine 31 to move and translate along the direction vertical to the conveyor belt 1, and the angle regulator 7 enables the laser marking machine 31 to carry out certain pitch angle regulation.

In addition, in order to further accelerate the feeding efficiency of the workpiece (crankshaft), as shown in fig. 5, the workpiece (crankshaft) is conveyed by the conveyor belt 1; specifically, a plurality of code printing platforms 2 are provided, and the code printing platforms 2 are all fixed on the conveyor belt 1 in sequence; in addition, the marking platform 2 is composed of a plurality of v-shaped support blocks arranged side by side, so that a workpiece (crankshaft) can be placed on the plurality of v-shaped support blocks.
