[0005] The present invention provides a multi-axis precision motion platform for LED cutting, specifically including: an equipment base; the equipment base is placed on the workbench, and four insertion rods are inserted into the top surface of the equipment base, and one end above the four insertion rods is fixed on the sliding frame A; a sliding frame B slides on the sliding frame A, and two second electric cylinders are fixed on the sliding frame A, and the extending ends of the two second electric cylinders are fixed on the sliding frame B.

[0007] Further, the sliding frame A, the insertion rods, the sliding frame B, the second electric cylinders, the clamping blocks, and the third electric cylinders together form a clamping assembly, and both of the two clamping blocks are L-shaped block structures.

[0008] Further, an auxiliary assembly is installed on the equipment base, and the auxiliary assembly is composed of a frame body and a hydraulic cylinder. Two concave-shaped frame bodies are fixed on the equipment base, and a hydraulic cylinder is fixed on the top surface of the inner wall of each frame body, and the extending ends of the two hydraulic cylinders are fixed on the sliding frame A.

[0009] Further, an adjustment component is installed on the equipment base. The adjustment component is composed of a sliding block, a guide rod A, a seat body, a first linear motor, a first electric cylinder, a base block, a rotating shaft, a mounting seat, a worm gear, a worm, a servo motor, and a second linear motor. Two sliding blocks slide on the equipment base, and two first linear motors are installed on the equipment base. The two sliding blocks are driven back and forth by the two first linear motors.

[0010] Further, a guide rod A is welded to the top surface of each sliding block. A seat body slides on the two guide rod As. The seat body is of a concave structure. A first electric cylinder is fixed on each sliding block, and the extending ends of the two first electric cylinders are fixed on the seat body.

[0011] Further, a base block slides on the seat body. A second linear motor is fixed on the seat body. The base block is driven left and right on the seat body by the second linear motor. A rotating shaft rotates on the base block. A mounting seat for installing a cutting laser head is welded on the rotating shaft. A worm gear is welded on the rotating shaft. A worm rotates on the base block. The worm meshes with the worm gear. A servo motor is fixed on the base block, and the output shaft of the servo motor is fixed on the worm.

[0012] Further, a cleaning component is installed on the equipment base. The cleaning component is composed of a sliding groove, a connecting block, a guide rod B, a cleaning block, a mounting arm, and an electromagnet. A sliding groove is opened on each of the left end face and the right end face of the equipment base. A connecting block slides in each sliding groove. A guide rod B is welded to the top of each connecting block. A cleaning block slides on the two guide rod Bs. The cleaning block is of a rectangular block structure.

[0013] Further, a mounting arm is welded to the outside of each connecting block. An electromagnet is fixed to the upper end of each mounting arm. The two electromagnets are respectively in contact with the two sliding blocks.

[0014] Further, the two sliding grooves are both of a T-shaped groove structure and are obliquely opened.

[0015] The present invention provides a multi-axis precision motion platform for LED cutting, having the following beneficial effects: In terms of structural design, installation and maintenance: The top surface of the equipment base is plugged and connected to the sliding frame A through four insertion rods. This detachable connection design brings great convenience to the cleaning work of the top surface of the equipment base. During subsequent cleaning, only by detaching the four insertion rods from the equipment base can the cleaning operation be directly carried out on the top surface of the equipment base, without complex disassembly processes, effectively saving maintenance time and improving the convenience of equipment maintenance. At the same time, the clamping assembly composed of components such as the sliding frame A, the insertion rods, and the sliding frame B has a compact and reasonable structural design. Both clamping blocks are L-shaped block structures. When placing parts, the parts are placed at the bends of the two clamping blocks. This structural design can effectively prevent the parts from falling when the height of the clamping blocks is adjusted subsequently, ensuring the stability of the part placement and providing a reliable basis for subsequent cutting operations.

[0016] In terms of the flexibility and accuracy of part position adjustment: The two second electric cylinders fixed on the sliding frame A have their extending ends fixed on the sliding frame B. By driving the telescoping of the two second electric cylinders, the left and right position adjustment of the sliding frame B can be accurately realized, and then the left and right position adjustment of the parts can be realized. This function can be used as an emergency adjustment part when the second direct row motor is damaged, ensuring that the equipment can still perform a certain degree of position adjustment in case of emergencies, improving the reliability and emergency handling ability of the equipment. The two clamping blocks on the sliding frame B perform the clamping action through two third electric cylinders fixed inside. When it is necessary to clamp the parts, drive the two third electric cylinders to extend, driving the two clamping blocks to move inward to complete the clamping, which is simple to operate and the clamping is firm. When it is necessary to make an emergency adjustment of the parts forward, drive the front third electric cylinder to contract and drive the rear third electric cylinder to extend at the same speed. In this way, the forward adjustment of the parts can be realized, and the adjustment method is flexible and diverse, meeting the requirements for part position adjustment in different scenarios.

[0017] The auxiliary components installed on the equipment base have the extending ends of the two hydraulic cylinders fixed on the sliding frame A. By driving the contraction and extension of the two hydraulic cylinders, the sliding frame A can be driven to move up and down, thus completing the height adjustment of the parts and realizing the precise positioning of the parts in the vertical direction. In terms of the accuracy and diversity of laser head adjustment, the adjustment component plays a key role.

[0018] Two sliding blocks on the equipment base are driven back and forth by two first linear motors. When it is necessary to adjust the front and back positions of the laser head, drive the two first linear motors to work, and the front and back adjustment of the sliding block and the laser head can be realized, ensuring that the laser head can accurately align with the cutting position of the part in the front and back directions. The second linear motor fixed on the seat body can drive the base block and the laser head to adjust the left and right positions, realizing the precise movement of the laser head in the left and right directions, and further improving the cutting accuracy; the servo motor on the base block can complete the angle adjustment of the laser head through the meshing transmission of the worm and the worm gear; this design enables the laser head to be adjusted to a suitable angle according to different cutting requirements, greatly increasing the applicable range of the equipment and meeting the cutting requirements of various complex shapes and angles.

[0019] In terms of the automation and efficiency of equipment cleaning: In the inclined T-shaped sliding grooves opened on the left and right end faces of the equipment base, a connecting block with a guide rod B and a cleaning block is slidably connected, and the electromagnet on the mounting arm contacts the sliding block; when it is necessary to clean the top surface of the equipment base, drive the hydraulic cylinder to contract to separate the frame body, the electromagnet is energized and adsorbed on the sliding block, and the sliding block is driven to move by the first linear motor, thereby driving the cleaning block to complete the cleaning work. This automatic cleaning method eliminates the need for manual operation, improves the cleaning efficiency, and the inclined sliding groove design enables the cleaning block to automatically reset after the electromagnet is powered off, ensuring the stability and reliability of the cleaning component, effectively maintaining the cleanliness of the equipment working environment, and reducing the impact on equipment operation and cutting accuracy caused by debris accumulation.
