Marking machine with hub type identification and method for product traceability of the marking machine

Abstract

The invention relates to the technical field of machinery. A marking machine with a wheel hub type identification function comprises a frame, a marking mechanism and a laser scanning mechanism, wherein the frame is provided with a conveying roller way for conveying a wheel hub and a lifting rotating clamping mechanism for clamping the wheel hub to move and rotate along the vertical direction; theframe is provided with a wheel hub type identification device for collecting appearance feature information of the wheel hub; the marking mechanism is arranged on the frame and is located below the conveying roller way, the marking mechanism comprises a pneumatic marking head and a three-dimensional motion assembly driving the pneumatic marking head to conduct three-dimensional motion; and the laser scanning mechanism comprises a laser scanning machine and a two-dimensional motion assembly driving the laser scanning machine to conduct two-dimensional motion in the horizontal and vertical directions, and the two-dimensional motion assembly is connected to the laser scanning machine. By replacing the tradition laser marking head with the pneumatic marking head, two modes of thermal marking and cold state marking are realized and the marking quality is excellent.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a marking machine and a product traceability method. Background technique [0002] Marking the wheel hub is an essential process in the wheel hub manufacturing process. [0003] For this process, the traditional way is to use manual marking, which is inconvenient and labor-intensive. To solve this problem, dot matrix pneumatic marking machines and laser marking machines were born. [0004] For the laser marking machine, there are the following problems: [0005] (1) After the marking of the laser marking machine undergoes a heat treatment process at a high temperature of 500°C, it will often be deformed and affect the marking quality. Marking, but this lacks the traceability of the quality of the wheel hub before the heat treatment process, and it is impossible to realize the quality control of each link in the wheel hub production process. [0006] (2) The laser marking m...

Problems solved by technology

[0005] (1) After the marking of the laser marking machine undergoes a heat treatment process at a high temperature of 500°C, it will often be deformed and affect the marking quality. Marking, but this lacks the traceability of the quality of the wheel hub before the heat treatment process, and it is impossible to realize the quality control of each link in the wheel hub production process

[0006] (2) The laser marking machine has requirements for the working environment and is not resistant to high temperature. After the heat treatment, the wheel hub needs to be cooled before marking, which cannot achieve hot marking, which prolongs the production cycle of the wheel hub

[0007] (3) The laser marking machine needs to flip the wheel hub before marking, and the industrial robot used to flip the wheel hub is expensive.

[0009] (1) The product structure of the marking machine is fixed, it cannot be customized, and it cannot meet the shape of the wheel hub, which is easy to interfere
