Embodiment Construction

[0065] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment of various embodiments of the present invention.

[0066] Refer to figure 1 figure 2 , The pneumatic marking machine in this embodiment mainly includes two parts, the circuit and the air circuit.

[0067] 1. Gas path:

[0068] The air circuit device adopts SMC's ISE30 digital pressure sensor, which is connected to the outlet of the main air inlet pneumatic two-piece, used to detect the main air pressure, and set the lowest critical air pressure to 4MPa.

[0069] 2. Circuit:

[0070] The power supply voltage of ISE30 digital pressure sensor adopts DC24V. When the air pressure is normal (greater than 4MPa), KA2 is energized, the normally closed contact KA2 in the air pressure detection circuit is opened, and the buzzer does not work (no alarm). When the air pressure is lower than the pressure value (4MPa) set by the pressure detection element, the ...

Abstract

The invention relates to a pneumatic number printer, having a air pressure detection device integrated thereon for detecting air pressure of the pneumatic number printer. The number printer is reliable and convenient in use, capable of ensuring stability of air pressure, applying engraving force, prevents the phenomenon of different depth and inclined characters of engraved vehicle body number and VIN number, enhances yield during vehicle body number or VIN number printing, lowers scrappage due to disqualification of vehicle body number or VIN number, so that stability of printed number is enhanced.

Description

Technical field [0001] The invention relates to the application of a pneumatic marking marking machine, in particular to a pneumatic marking marking machine with an air pressure detection device. Background technique [0002] The number marking equipment in the prior art is mainly distributed in the final assembly and welding assembly, and is used for marking the serial number of the car body (divided into hidden numbers and visible numbers) and marking the VIN code. The requirements for marking equipment in the final assembly and welding also have their own characteristics, especially the VIN code number. The characteristics of marking in the final assembly are: [0003] 1. It is printed after the final assembly and has been painted, which has high requirements for the reliability of the fixture, the reliability of the marking and the performance of the overall equipment. [0004] 2. The equipment is required to be trouble-free and have a high intact rate. [0005] 3. The requir...
