Description

Technical Field

[0001] The utility model relates to the technical field of laser engraving, in particular to an automatic loading and unloading device for laser engraving equipment. Background Art

[0002] A laser engraving machine uses a laser beam to create a permanent mark on a surface or inside a transparent material. Laser beams can produce both chemical and physical effects on materials. When the material absorbs the laser light, a physical or chemical reaction occurs, creating a mark or displaying a pattern or text. This is why it's also called a laser marking machine or laser engraving machine.

[0003] Laser engraved SN codes, short for laser engraved serial numbers, are serial numbers inscribed on various materials using laser technology. They offer advantages such as anti-counterfeiting and fade resistance, making them commonly used for marking materials such as metal, plastic, and glass. They are often used in electronics manufacturing, marking production dates and batch numbers, and logistics management. In electronics manufacturing, laser engraved SN codes can be used to identify product information such as model, specifications, and serial numbers, facilitating production management and quality control.

[0004] Existing laser engraving equipment typically consists of a laser engraving machine on top and a product positioning platform at the bottom. Typically, the product is manually fixed to the platform at the bottom of the laser engraving machine, then the laser engraving machine laser engraves the corresponding position on the product. The product is then manually removed to complete the processing process. However, manual loading and unloading, and the need for dedicated personnel to operate a single machine, are time-consuming and labor-intensive, resulting in low processing efficiency and a high labor consumption.

[0020] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0021] Example: Figure 1-Figure 3 As shown, an automatic loading and unloading device for laser engraving equipment includes a frame 1, on which a loading conveyor belt 2, a laser engraving workbench 3 and a unloading conveyor belt 4 are arranged from left to right. The laser engraving workbench is the laser engraving processing position and is arranged corresponding to the position directly below the laser engraving machine. A baffle is arranged at the tail end of the loading conveyor belt, which is the loading and conveying position, and the initial end of the unloading conveyor belt is the unloading and conveying position. Slide rails 5 distributed from left to right are arranged on the rear side of the frame, and a horizontal moving platform 6 is slidably connected to the slide rail. The horizontal moving platform is pushed left and right along the slide rail by a pushing cylinder. The pushing cylinder is installed on the frame, and a lifting cylinder 7 is installed on the horizontal moving platform. A lifting frame 8 is fixedly installed on the output end of the lifting cylinder. Suction cup assemblies for vacuum suction and placement of products are respectively arranged at the left and right ends of the lifting frame. The spacing between the loading and conveying position, the laser engraving processing position and the unloading conveying position is the same, corresponding to the spacing between the two suction cup assemblies.

[0022] The heights of the loading conveyor belt, laser engraving workbench and unloading conveyor belt are consistent.

[0023] like Figure 4 As shown, a universal positioning base is installed on the laser engraving workbench. The universal positioning base is provided with corresponding positioning pin holes 12 and vacuum holes 13 for positioning products of various specifications. The positioning pin holes are used to install positioning pins, and the vacuum holes are connected to the vacuum adsorption equipment. The product is positioned by inserting the positioning pins in the positioning pin holes and adsorption through the vacuum holes.

[0024] The suction cup assembly includes an adjustment plate 9, a suction cup mounting frame 10 and a suction cup 11. The suction cup is connected to a vacuum pump. Multiple rows of mounting holes are provided on the adjustment plate. The suction cup mounting frame is provided with longitudinal waist-circular holes for adjusting and installing with the corresponding mounting holes on the adjustment plate through bolts, and installing the suction cup. The position of the suction cup is adjusted and installed at a suitable position along the longitudinal waist-circular holes.

[0025] The lifting frame is equipped with two longitudinal waist-shaped grooves on each end, which are used to adjust the mounting holes on the corresponding adjustment plate via bolts. The loading conveyor belt is driven by the loading motor, which is mounted on the frame. The unloading conveyor belt is driven by the unloading motor, which is also mounted on the frame.

[0026] This automatic loading and unloading device for laser engraving equipment uses the longitudinal grooves on the lifting frame to adjust the suction cups' mounting positions to the corresponding products. When the loading conveyor belt delivers the product to the loading position until it contacts the baffle, the push cylinder drives the horizontal movable platform to the corresponding position. The lifting cylinder descends, and the suction cup assembly on the left end of the lifting frame picks up the product to be processed at the loading position. Simultaneously, the suction cup assembly on the right end of the lifting frame picks up the finished product at the laser engraving position. The lifting cylinder then rises, driving the lifting frame upward. Simultaneously, the push cylinder activates, driving the horizontal movable platform to the right to the corresponding position at the unloading position. The lifting cylinder descends, and the suction cup assembly on the left end of the lifting frame places the product to be processed on the laser engraving position for processing. Simultaneously, the suction cup assembly on the right end of the lifting frame places the finished product on the unloading conveyor belt for automatic unloading. This reciprocating process achieves automatic loading and unloading of the laser engraving equipment.

[0027] The embodiment described above is only a preferred solution of the present invention and does not limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
