Description

Technical Field

[0001] The utility model belongs to the field of laser processing equipment, and in particular relates to a processing equipment with opposite-type double laser heads. Background Art

[0002] Laser processing technology can be categorized into two types, laser thermal processing and photochemical reaction processing, based on the interaction between the laser beam and the material. Laser thermal processing utilizes the thermal effect generated by a laser beam projected onto a material surface to complete the processing process. Examples include laser welding, laser engraving and cutting, surface modification, laser marking, laser drilling, and micromachining. Photochemical reaction processing involves irradiating an object with a laser beam, initiating or controlling a photochemical reaction using high-density, high-energy laser photons. Examples include photochemical deposition, stereolithography, and laser engraving and etching. Laser marking is a new processing technology that has developed following the application of laser welding, laser thermal treatment, laser cutting, and laser drilling. It is a non-contact, pollution-free, and wear-free marking process. The increasing reliability and practicality of lasers, coupled with the rapid development of computer technology and improvements in optical devices, have fueled the development of laser marking technology. Laser marking offers advantages such as high speed, clear and permanent marking, non-contact processing, minimal pollution, no wear, ease of operation, and strong anti-counterfeiting capabilities. It also enables high-speed automated operation and low production costs. As a modern precision machining method, laser marking offers unparalleled advantages over traditional machining methods such as printing, etching, EDM, and mechanical scribing. It enables high-precision positioning and calibration, meeting the high-precision machining requirements of the industrial sector and is widely used in the automotive, aerospace, electronics, and machinery sectors.

[0003] Generally, laser processing platforms can only process and mark workpieces within a specified range, such as 800mm×800mm. However, for some longer products, such as couplets, they cannot be marked directly because the table length is not enough. When marking longer products, problems such as poor table adaptability arise. Summary of the Invention

[0004] In response to the problems in the related technology, the utility model proposes a facing dual laser head processing equipment. By setting the two frames and their laser marking equipment facing each other, the two marking tables are connected into one to form a longer marking platform, so that longer products can be directly marked as a whole.

[0005] The utility model is achieved in this way:

[0006] A processing device with two opposing laser heads includes a frame and a laser marking device arranged on the frame, wherein a marking platform is provided at the lower end of the laser marking device, and the marking platform is fixedly connected to the frame;

[0007] The frame is provided with a marking table on one side, and is also provided with a frame identical to the frame, the frame is provided with the same laser marking device and marking table, the two marking tables are positioned opposite to each other and connected to each other to form a marking platform, the marking platform is formed in one piece, the two laser marking devices are positioned opposite to each other and are respectively located above the marking tables on their sides, and the laser marking devices move up and down along the frame they are located on; a connecting frame is provided at the lower end of the marking platform, and the frame is fixed to both ends of the connecting frame; the marking areas covered by the two laser marking devices in the middle of the marking platform overlap with each other;

The slider and the slide rod can prevent the direction of the laser marking device from shifting when it moves up and down.

[0017] Preferably, the laser marking equipment is fixed on a lifting frame, and the lifting frame includes two side plates and a support plate and a back plate located between the two side plates.
