Description

Technical Field

[0001] This utility model relates to the field of laser etching machine technology, and in particular to a large-format laser etching machine. Background Technology

[0002] Currently, most laser etching machines have their laser heads fixed above the table by a column. Therefore, the processing area of ​​the laser head is limited during the laser etching process, generally not exceeding 30mm*30mm, which limits the products that can be processed.

[0003] A large-format laser etching machine is proposed in patent publication number CN219358259U. This patent includes a stage, a gantry, a laser head, a moving mechanism, guide rails, a moving beam, a rack, a motor, and a lighting fixture. By mounting the laser head on the gantry, it overcomes the technical prejudice that laser heads can only be installed inside frame-type machines, raising the focal point and increasing the focal length of the laser head, thereby expanding the processing width of the product and solving the difficulty of small processing width. By setting the laser head as a dynamic focusing engraving head and setting a moving mechanism on the gantry to drive the linear movement of the laser head, the laser head can adjust the focal point in four-axis linkage, further increasing the processing width of the product. The lighting fixture allows for real-time observation of the product surface during or after processing, reducing the occurrence of dust and particulate matter adhering to the product surface and affecting processing. However, this patent still has the following problems: Existing etching machines can only be moved in one direction and cannot be adjusted in height to modify the etched structure, making them inconvenient to use.

[0004] To address the above problems, a large-format laser etching machine needs to be designed to overcome them. Utility Model Content

[0005] The main objective of this invention is to provide a large-format laser etching machine that can effectively solve the problems in the background art.

[0017] like Figures 1-4 As shown, a large-format laser etching machine includes a base plate 1, an etching worktable 2 installed in the middle of the top of the base plate 1, a support column 3 installed at one end of the top of the base plate 1, a support plate 4 installed on the top of the support column 3, and an adjustable etching mounting assembly 5 provided on one side of the support plate 4. The adjustable etching mounting assembly 5 includes a guide frame 501 disposed on one side of the support plate 4, a servo motor 502 mounted on one side of the guide frame 501, a coupling 503 mounted on one side of the servo motor 502, a lead screw 504 disposed on one side of the coupling 503, a linear motion guide rail 505 mounted on one side of the guide frame 501, a limit nut 506 mounted on one end of the outer wall of the lead screw 504, connecting rods 507 mounted on both sides of the limit nut 506, moving blocks 508 mounted on the upper and lower sides of the two connecting rods 507, a limit panel 509 mounted on one side of the two moving blocks 508, a limit block 510 mounted on the side of the limit panel 509 away from the coupling 503, and a fixing bracket 511 mounted on the side of the limit block 510. A motor 512 is installed at the top of the fixed frame 511. A drive shaft 513 is installed through the bottom of the motor 512 and through the top of the fixed frame 511. A protective cavity 514 is installed at the bottom of the fixed frame 511. A lifting rod 515 is installed through the bottom of the drive shaft 513 and through the bottom of the fixed frame 511. A lifting block 516 is installed on the outer wall of the lifting rod 515. An installation rod 522 is installed on the right side of the lifting block 516. A fixed guide rail 517 is installed at one end of the outer wall of the installation rod 522. A moving plate 518 is installed on the right side of the fixed guide rail 517. A reinforcing plate 519 is installed on the right side of the moving plate 518. A laser head mounting plate 520 is installed at the lower end of the right side of the reinforcing plate 519. A laser 521 is installed at the top of the laser head mounting plate 520. The servo motor 502 is connected to the lead screw 504 via the coupling 503. The guide frame 501 is fixedly connected to the linear motion guide rail 505. The lead screw 504 is threadedly connected to the limit nut 506. The limit nut 506 is threadedly connected to two connecting rods 507. The two connecting rods 507 are threadedly connected to two moving blocks 508. Both sides of the two moving blocks 508 are in contact with the inner side of the linear motion guide rail 505. The two connecting rods 507 are fixedly connected to the limit panel 509. The limit panel 509 is fixedly connected to the limit block 510. The limit block 510 is threadedly connected to the fixed frame 511. The screw 504 rotates, which drives the limit nut 506 to rotate, causing the two moving blocks 508 to move linearly on the inner side of the linear guide rail 505. This facilitates the movement of the limit panel 509, thereby making it easier to adjust the position of the laser 521. The limit nut 506 can limit the use of the screw 504. The limit panel 509 and the limit block 510 can improve the connection and reinforcement between the guide frame 501 and the fixed frame 511, thereby improving the stability of the etching process. Motor 512 is connected to lifting rod 515 via drive shaft 513. Lifting rod 515 is threaded to lifting block 516, and lifting block 516 is threaded to mounting rod 522. The right side of mounting rod 522 is threaded to the left side of reinforcing plate 519, and mounting rod 522 is threaded to fixed guide rail 517.

Reinforcing plate 519 is fixedly connected to laser head mounting plate 520, and laser head mounting plate 520 is fixedly connected to laser 521. The lifting rod 515 drives the lifting block 516 to move within the protective cavity 514. The mounting rod 522 on the right side of the lifting block 516 is used to adjust the movement plate 518 to rise and fall on the fixed guide rail 517, thereby adjusting the laser head at the bottom of the laser head mounting plate 520 to etch the product on the etching worktable 2, which is convenient for adjustment and use.

[0018] It should be noted that this utility model is a large-format laser etching machine. In use, the product to be etched is placed on the etching worktable 2. The servo motor 502 drives the coupling 503 to rotate the lead screw 504, which in turn rotates the limit nut 506. This causes the two connecting rods 507 to move linearly along the inner side of the linear guide rail 505, adjusting the position of the fixing frame 511. Then, the motor 512 drives the lifting rod 515 to raise and lower the lifting block 516. The mounting rod 522 then moves the moving plate 518 to the right side of the lifting block 516. The laser head mounting plate 520 is adjusted to change the distance between itself and the etching worktable 2, allowing for easy adjustment and use. The protective cavity 514 provides protection for the lifting rod 515 and the lifting block 516. The lead screw 504 is guided and limited by the limit nut 506 when rotating. The connecting rod 507 facilitates the installation of the moving block 508 and allows for easy adjustment of the position of the limit panel 509 that drives the fixed frame 511. The reinforcing plate 519 improves the stability of the laser head mounting plate 520 during use.
