Description

Technical Field

[0001] The utility model relates to the technical field of marking machines, in particular to an external magnetic field strength detection tool. Background Art

[0002] Marking machine is a kind of equipment used for marking, lettering, engraving and other operations on the surface of different materials. It uses laser, inkjet, electro-etching, engraving and other technologies to permanently mark text, patterns, barcodes and other information on objects. Marking machine can be applied to a variety of materials, including metal, plastic, glass, ceramics, wood, etc., and is widely used in industrial production, manufacturing, jewelry, medical equipment, electronic products and other fields. It uses laser beam to oxidize, evaporate or dissolve the surface of the material to achieve high-precision and high-speed marking and lettering. Laser marking machine is suitable for a variety of materials and has the advantages of non-contact operation, clear marking and good durability. Marking machine plays an important role in industrial manufacturing, product management and marketing. It can improve the effect of product identification, anti-counterfeiting traceability, information transmission and brand promotion, and can also realize product beautification and personalized customization. However, during the installation of the existing marking machine, it was found that the magnetic field strength of the magnetic steel outside some workpieces was weak and could not meet the use requirements. The probability of this happening is extremely low, and it is impossible to find it by conventional sampling means. If a single process is used for full inspection, the cost will increase. Therefore, those skilled in the art provide an external magnetic field strength detection tool to solve the problems raised in the above background technology. Utility Model Content

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: when the marking machine needs to be used for work, the flywheel is placed on the workbench of the marking machine, the working button on the marking machine controller is pressed, the laser sensor detects whether the flywheel is in the specified position, the laser detection is in place, and the signal is transmitted to the magnetic field detection box through the connecting line. The left end of the magnetic field detection box has a magnetic field detection box body connection port to connect the connecting line, and the signal enters the Hall sensor in the magnetic field detection box for detection. At this time, if the flywheel magnetic field intensity is high, the Hall sensor triggers the relay, turns on the marking machine start button, and the marking machine and the marking head work. If the magnetic field is weak and cannot trigger the Hall sensor, the relay turns on the alarm, and the alarm controls the buzzer to sound an alarm. The alarm controls the red light on the main body of the alarm light to flash to remind the operator that the magnetic field of the workpiece is weak. When the magnetic field strength is high, the green light on the main body of the alarm light is on and the marking machine works normally. When the marking machine stops working, the yellow light on the main body of the alarm light is on. People can identify the strength of the magnetic field of the marking machine and the working status of the marking machine through the light on the main body of the alarm light. Without increasing the manufacturing cost, the goal of passing the full inspection of the flywheel external magnetism is achieved, and intuitive visual and auditory prompts are provided to ensure the safe operation of the marking machine and the quality of the workpiece. Comprehensive magnetic field detection can be achieved by adding only some simple components, which can greatly improve the production efficiency of the marking machine and reduce the cost of maintenance and repair.
