[0001] The present invention relates to the technical field of laser cutting machines, in particular to a parts identification and coding device for an exchange workbench of a laser cutting machine. Background Art

[0002] Laser cutting machines are widely used in the sheet metal production industry. During the production process of sheet metal cutting parts, managing the types and quantities of sheet metal parts after cutting is often very time-consuming and labor-intensive. Pre-processed sheet metal parts of various shapes and quantities are arranged on the metal sheet. After production, the sheet metal parts are piled up together and difficult to classify and manage. During the laser cutting process of the sheet metal, production personnel can rely on to identify sheet metal parts of different shapes and give them different marks. However, relying on manual execution of this process has many disadvantages. First, manual identification of the shape of sheet metal parts is time-consuming and labor-intensive, which will extend production time and reduce economic benefits.

DETAILED DESCRIPTION

[0020] In order to achieve the above-mentioned objectives and effects, the technical means and structures adopted by the present invention are described in detail with reference to the accompanying drawings for the features and functions of the preferred embodiments of the present invention.

[0021] like Figure 1-3 As shown, the present invention provides a parts identification and coding device for a laser cutting machine exchange workbench, comprising:

[0022] X-axis motion system 1, wherein two X-axis motion systems 1 are provided and are fixedly arranged on both sides of the workbench of the laser cutting machine;

[0023] Y-axis motion system 2, the Y-axis motion system 2 is arranged on the working slide of the X-axis motion system 1;

[0024] A Z-axis motion system 3, which is arranged on the working slide of the Y-axis motion system 2;

[0025] A visual inspection system 4 is provided on top of the working slide of the Y-axis motion system 2 and is used to detect and identify the cut plate parts;

[0026] The laser marking system 5 is arranged on the side of the working slide of the Z-axis motion system 3 and is electrically connected to the visual inspection system 4, and is used to mark the plate parts identified by the visual inspection system 4 with corresponding marks.

[0027] As a preferred embodiment, the X-axis motion system 1, the Y-axis motion system 2 and the Z-axis motion system 3 all adopt a screw slide motion system.

[0028] As a preferred embodiment, the laser marking system 5 includes a U-shaped bracket 51, which is fixedly connected to the working slide of the Z-axis motion system 3. The lower bracket of the U-shaped bracket 51 is provided with a spherical bearing 57, in which a laser marking machine head 59 is fixedly installed. The top of the laser marking machine head 59 is provided with a rod end spherical joint 6. The upper bracket of the U-shaped bracket 5 is provided with a rotating slide 52. The turntable of the rotating slide 52 is radially eccentrically provided with an electric cylinder 53. The working end of the electric cylinder 53 is provided with a slide 55, and the bottom of the slide 55 is provided with a sliding sleeve 56, which is slidably connected to the rod end spherical joint 6. Since sheet metal parts after laser cutting will deviate if the worktable support frame cannot stably support them, resulting in an uneven marking surface, which is prone to unclear marking or missing marks, this arrangement allows the laser marking machine head 59 to achieve universal motion to adapt to sheet metal parts at different angles and ensure the marking effect.

[0029] In the above embodiment, the rod-end spherical joint 6 includes a ball pin 63, a ball seat 62 and a slide rod 61; the rod portion of the ball pin 63 is fixedly connected to the top of the laser marking machine head 59; the ball portion of the ball pin 63 is semi-enclosed in the ball seat 62 and slides relative to the ball seat 62; the side of the ball seat 62 opposite to the ball pin 63 is fixedly connected to the slide rod 61; the slide rod 61 is inserted into the interior of the sliding sleeve 56.

[0030] In the above embodiment, a slide rail 54 is further provided on the turntable of the rotary slide 52, and the slide rail 54 is adapted to the slide plate 55. The provision of the slide rail 54 can improve the stability of the sliding.

[0031] In the above embodiment, at least three distance measuring sensors 58 are evenly distributed on the lower bracket of the U-shaped bracket 51. Using the principle of three points on one plane, the angle of the cut sheet material is determined. The angle of the laser marking machine head 59 is then adjusted using the rotary slide 52 and electric cylinder 53 until the distances between the three points are the same. The Z-axis motion system 3 then adjusts the focusing distance of the laser marking machine head 59 to perform laser marking.

[0032] The above descriptions are only preferred embodiments of the present invention, not all embodiments. Anyone should be aware that any structural changes made under the guidance of the present invention, and any technical solutions that are the same or similar to those of the present invention, fall within the scope of protection of the present invention.
