Description

Technical Field

[0001] This utility model relates to the field of laser engraving machine technology, and in particular to a precision mold conveying device for laser engraving machines. Background Technology

[0002] With the rapid development of science and technology and the continuous advancement of industrial automation, the demand for efficient and accurate production equipment in the precision manufacturing industry is constantly increasing. Against this backdrop, laser engraving technology, as a high-precision engraving process, is widely used in industries such as electronics, communications, medical, and automobiles. In the laser engraving process, the role of the mold conveying device is to accurately deliver the item to be engraved into the working area of ​​the laser engraving machine.

[0003] The precision mold conveying device of the laser engraving machine mainly consists of a support base, a conveyor belt, a U-shaped support base, and an engraving head. The mold is placed on the conveyor belt, and under the stable support of the support base, the conveyor belt drives the mold forward. The U-shaped support base ensures that the conveyor belt and the mold move smoothly along the predetermined path. When the mold is conveyed to the engraving station directly below the engraving head, the conveyor belt stops running, and the engraving head starts to perform laser engraving on the workpiece on the mold. After completion, the conveyor belt starts again to convey the mold to the next stage.

[0004] In the existing technology, some precision mold carrier conveying devices for laser engraving machines use a single fixed method. When faced with different shapes of mold blocks, the fixed centering structure is difficult to adapt to the differences in the shape of the mold blocks, and cannot quickly and accurately find the center position of the mold block. This affects the positioning accuracy and stability of laser engraving, thereby reducing the processing efficiency. In order to address the above problems, a precision mold carrier conveying device for laser engraving machines is proposed. Utility Model Content

[0020] As a further description of the above technical solution:

[0021] A U-shaped support is fixedly connected to the top of the support base, a sliding block is slidably connected to the outside of the U-shaped support, an engraving head is fixedly connected to the front side of the sliding block, a control screen is fixedly connected to the bottom left side of the support base, a film support is fixedly connected to the outside of the conveyor belt, and a film block is slidably connected to the top of the film support.

When the follower block rotates, it pushes the connecting block to slide on the limiting support block a, causing the support rod and the U-shaped fixing rod to move in a centered position. This ensures that the film support seat can center and fix film blocks of different shapes. At the same time, the film blocks are transported by a conveyor belt to ensure that the position of the film blocks is stable, reduce processing errors, and improve processing accuracy, stability and efficiency.

[0024] 2. In this utility model, when the engraving head processes the carrier film, water is drawn from the supporting water tank by a water pump and evenly sprayed onto the surface of the film block through the connecting pipe and threaded nozzle to achieve a cooling effect. At the same time, the water inlet pipe introduces water into the water tank, and the water flow is regulated by controlling the pump to ensure stable operation of the system. The threaded nozzle and connecting pipe can be quickly replaced, and the observation tube facilitates real-time monitoring of the water level. This not only improves the convenience of operation but also effectively enhances the cooling effect during the processing. Attached Figure Description

The conveyor belt 2 mainly conveys the mold, improving processing efficiency and ensuring the smoothness of the conveying process. An alignment and fixing mechanism is provided inside the support base 1, including two limiting support blocks a11. The limiting support blocks a11 ensure the accuracy and stability of the sliding of the supporting connecting plate 10. The bottoms of the two limiting support blocks a11 are fixedly connected to the inside of the support base 1, and the top of the limiting support blocks a11 is slidably connected to the supporting connecting plate 10. As the top of the limiting support blocks a11 slides, the support rod 15 and the rotating follower block 13 connected to their tops move accordingly.

A film support seat 16 is fixedly connected to the outside of the conveyor belt 2. The film support seat 16 is fixed to the outside of the conveyor belt 2 and moves with the movement of the conveyor belt 2 to transport the membrane block 17 to the processing position. At the same time, under the action of the centering and fixing mechanism, the centering and fixing of the membrane block 17 is completed. The membrane block 17 is slidably connected to the top of the film support seat 16. The membrane block 17 is used to store the raw materials used during processing.

[0037] Working principle: First, the cylinder 7 is started, which drives the follower telescopic rod 8 to extend and retract. At the same time, it pushes the connecting block 9 to slide on the limiting support block b12. While the connecting block 9 is sliding, it drives the rotating follower block 13 to rotate. While the rotating follower block 13 is rotating, the two pushing connecting blocks 9 slide on the limiting support block a11, which drives the support rod 15 and the U-shaped fixing rod 14 to perform centering movement. Thus, when the film support seat 16 drives the film block 17 to be processed by the engraving head 6, the film block 17 is centered and fixed. At the same time, the film is conveyed by the conveyor belt 2. The centering and fixing of film blocks 17 with different patterns is completed stably and reliably, which effectively ensures the position of the film block 17 during processing, reduces processing errors caused by positioning deviations, improves the accuracy and stability of film block 17 processing, and improves processing efficiency.

[0038] Secondly, when processing the carrier film using the engraving head 6, water is drawn from the support storage water tank 18 by the water pump 26 and sprayed evenly onto the surface of the film block 17 through the connecting pipe 21 and the threaded nozzle 22 to cool the surface. At the same time, water enters the support storage water tank 18 through the inlet pipe 24. The control pump 25 controls the quick replacement of the threaded nozzle 22 and the connecting pipe 21. The observation pipe 23 can be used to observe the water level inside, which can effectively achieve real-time cooling during processing and improve the convenience of operation.
