Description

Technical Field

[0001] The utility model relates to the field of laser processing, in particular to a feeding mechanism of a laser processing machine. Background Art

[0002] Laser engraving processing is the most commonly used application of laser systems. According to the mechanism of the interaction between the laser beam and the material, laser processing can generally be divided into two categories: laser thermal processing and photochemical reaction processing. Laser thermal processing refers to using the thermal effect generated by the laser beam projected onto the material surface to complete the processing process, including laser welding, laser engraving and cutting, surface modification, laser marking, laser drilling, and microfabrication, etc.

[0003] In the utility model with the Chinese patent authorization announcement number "CN219852704U", a feeding mechanism of a laser processing machine is disclosed. The feeding device of the laser processing machine usually does not have a fixed limiting structure, and it is easy for parts to shift during transportation or processing, affecting processing. It includes a base, one side of the upper end of the base is connected with a laser processing device, the inside of the base is slidably connected with a feeding frame, and fixing components are connected to the four surrounding sides inside the feeding frame. In this utility model, when the electric adjusting rod extends, it drives the support frame to move, so that the fixing plate initially fixes the outside of the part. The double-shaft motor drives the rotating shaft to rotate, and under the driving action of the transmission belt, the second pulley drives the threaded rod to rotate, and then the round rod drives the limiting plate to move downward along a straight line, so that the limiting plate clamps and fixes the two parts. Under the double fixation of the fixing components, the parts to be processed are more stable during the transportation process and the processing process, avoiding shifting and affecting processing.

[0004] Regarding the above related technologies, the inventor believes that in the above utility model, although the parts can be kept more stable during the transportation process and the processing process, there is a lack of a cleaning component. During the laser processing process, especially operations such as cutting and grinding, a large amount of dust and debris will be generated. If these debris are not cleaned in time, it will inevitably affect the normal operation of components such as the threaded rod, round rod, and limiting plate.

[0005] Therefore, it is necessary to provide a new feeding mechanism of a laser processing machine to solve the above technical problems. Content of the Utility Model

A laser processing device is connected to the top of the mounting frame 1.

[0024] It should be noted that: The installation frame 1 is the support structure of the entire feeding mechanism, ensuring the stable and correct installation and operation of other components. The feeding frame 2 is connected to the installation frame 1 through a sliding connection and can move smoothly inside, facilitating the loading and conveying of materials. The material placement plate 3 is used to place the materials to be processed. Rotating assembly: It is arranged at the bottom on both sides of the feeding frame 2 and is connected through a driving gear 41 and a transmission rod 42, which can drive the material placement plate 3 to flip, helping to clean up the debris generated during the processing and keeping the processing environment clean. Fixing assembly: It is located at the bottom of the material placement plate 3 and is used to fix the materials to ensure that the materials do not move or slide during the processing, improving the processing accuracy.

The driving gear 41 is connected to the bottom of the feeding frame 2 through a bracket, and both ends of the transmission rod 42 are connected to the driving gear 41 to achieve synchronous driving.

[0025] In the embodiment of the present utility model, the fixing assembly includes a bidirectional screw 5 installed at the bottom of the material placement plate 3. Slide rods 51 are installed on both sides of the bottom of the material placement plate 3 where the bidirectional screw 5 is located.

The second driving member is a motor. Two fixing plates 53 are installed at the top of the material placement plate 3 and are fixed to the material through a sliding connection. The two sides of the bottom of the fixing plate 53 pass through the sliding grooves on the material placement plate 3 through the connecting plates and are connected to the two sides of the top of the sliding block 52. This enables the fixing plate 53 to move with the movement of the sliding block 52, ensuring the stable fixation of the material. The sliding grooves are arranged at the top of the material placement plate 3 and are located above the slide rod 51. The sliding grooves provide a movement path for the fixing plate 53, enabling it to slide smoothly with the movement of the sliding block 52. When the second driving member is started, it drives the bidirectional screw 5 to rotate. The bidirectional screw 5 drives the sliding block 52 to slide along the slide rod 51 through the thread. The movement of the sliding block 52 drives the fixing plate 53 to slide in the sliding groove through the connecting plate, realizing the clamping or releasing operation of the material.
