A laser engraver having a laser, a camera, and a plate for holding a product, wherein an optical path of the laser is directed to the plate, an optical path of the camera is directed to the plate, and the optical path of the camera to the plate and the optical path of the laser to the plate are at least partially the same before and when hitting the plate. The laser engraver includes a controller and a comparator, wherein the controller is configured to have the laser engrave a predefined pattern at a predefined position on the product on the plate to form an engraved pattern on the product and have the camera capture a position of the engraved pattern, have the comparator compare the predefined position and the position captured by the camera to determine a difference therebetween, and use the difference to calibrate the laser.

A method of forming a non-optically detectable identifiable marking invisible to the naked eye is formed from plural recesses of multiple levels at an outer surface of an article formed from a solid-state material. The method includes forming plural recesses of multiple levels within a predetermined region of a photoresist applied to an outer surface of an article formed from a solid-state material. The plural recesses are formed by grayscale lithography and the recesses extend at least partially through the photoresist and towards the outer surface of the article formed from a solid-state material. The method also includes applying an etching process such that at least a portion of the outer surface of said article is exposed and etched to form plural etched portions extending into the article from its outer surface and corresponding to plural recesses; wherein said predetermined region of said photoresist defines an identifiable marking to be applied to the outer surface of said article; wherein said plurality of etched portions forms the non-optically identifiable marking on the outer surface of said article.

Provided are an automatic continuous image engraving device capable of decreasing in size of an installing space of the device. The device comprises an unengraved medium accommodating part, an engraved medium accommodating part, a medium dispenser, a medium positioning and conveying part, and an image engraving part, wherein the medium dispenser releases the unengraved card-shaped engraving medium to cause the same to be succeeded at the succeeding position, the medium positioning and conveying part returns the engraved card-shaped engraving medium after image engraving from the engraving position to the succeeding position, and the medium dispenser adsorbs the engraved card-shaped engraving medium at the succeeding position, moves the same upward, travels above the engraved medium accommodating part, and releases the engraved card-shaped engraving medium to be accommodated.

The present invention provides for a wall mountable system for automated drawing of an image upon a wall which includes a horizontal mounting track for mounting on a wall, a robot having a y-track rigidly mounted it where the robot and the mounted y-track travel along the horizontal track. An end effector, which includes a pen holding mechanism holding a pen, is in electrical communication with the robot and travels along the y-track of the robot. The present invention provides a system and device that can attach to a wall or vertical surface in a damage-free manner and draw fast any complexity or style image of custom size in both the horizontal (X) and vertical (Y) directions, that is easy to remove and transport and require small floor space to operate.

The present disclosure provides an identification code recognition system, including: a camera configured to capture an image of an entire area of an identification code (ID code) engraved on a workpiece; a scanner configured to scan a partial area including at least one misrecognized character in the entire area of the ID code; and an image analyzer including a memory and a processor, wherein the memory is configured to store the ID code, data related to the ID code, an image captured by the camera, and an image scanned by the scanner, and the processor is configured to analyze the image captured by the camera and the image scanned by the scanner based on an image analysis logic.

The invention relates to a method for carrying out a test and measuring method on a flat test specimen (1), wherein a mechanical load is introduced into a test specimen surface (2) by means of a rotating engraving head (3) of an engraving device (4), wherein the engraving head (3) penetrates with a defined contact pressure at least into a layer system (5) applied to the test specimen (1), wherein the rotating engraving head (3) is moved along the test specimen surface (2) and relative to the test specimen (1) in order to create at least one engraving (6) on the test specimen surface (2) by plastic deformations and/or brittle chipping of the layer system (5), and wherein the at least one engraving (6) introduced into the test specimen surface (2) is measured using a photo-optical method in order to evaluate layer adhesion of the layer system (5) to the main body (11). The invention also relates to an engraving device (4) for carrying out such a method.

A method for verifying a marking (8), wherein compressed air is continually supplied to a needle piston (2), which oscillates in a needle head housing (7) of a marking head (1) and which has a needle (3) on one end, which inserts the marking (8) into a surface (4), pressure fluctuations are formed in a compressed air supply line (10) during the oscillation, compressed air is continually measured in the compressed air supply line (10), a pressure profile is created and is compared to a reference pressure profile stored in an evaluating unit (12) and is evaluated.

The present disclosure provides an ID number complement method for a engraving machine, including the steps of: sequentially acquiring a first distance a and a second distance g of a character located in a first digit of an identification number to an edge of an identification area in each identification area; respectively subtracting the first distance a and the second distance g from a first preset value a and a second preset value g, and acquiring an offset information in X-axis direction and Y-axis direction of the identification number in each identification area. The disclosure also provides an ID number complement system for an engraving machine, including: a measuring device, a statistical process control system and an engraving machine. Compared with the prior art, the automatic filling of the engraving machine is realized, and the working efficiency is improved by the above method.

A protective device for a processing machine is provided. The protective device includes one end portion including an opening portion, another end portion configured to be detachably attached to a tip end tool holding portion of processing machine, a main body portion extending in a predetermined direction from the other end portion to the one end portion and including a hollow portion communicating with the opening portion, and a spherical member rollably supported by the one end portion and protruding in the predetermined direction from an end surface of the one end portion.
