Description

Technical Field

[0001] This utility model relates to the field of fiber laser marking technology, and in particular to a rapid positioning structure for the worktable of a fiber laser marking machine. Background Technology

[0002] The rapid positioning structure of the worktable of a fiber laser marking machine is a core component for achieving efficient and accurate marking of workpieces. Its design needs to balance three core indicators: speed, accuracy, and stability, to ensure that the worktable can move quickly to the target position and stop stably, meeting the needs of high-frequency and high-precision marking.

[0003] In existing technology, this device receives coordinate commands of the marking pattern through a control system, calculates the distance the worktable needs to move, and the servo motor rotates according to the command, driving the worktable to move along the guide rail via a ball screw synchronous belt. The grating ruler detects the actual position of the worktable in real time and transmits the signal to the control system. The control system compares the "command position" with the "actual position," and if there is a deviation, it immediately adjusts the motor output until the worktable stops precisely. However, metal shavings, dust, and oil generated during the marking process easily adhere to the scale of the grating ruler, blocking light and causing loss and misreading of the reading head signal, leading to positioning errors. A "fully enclosed metal protective cover" is installed on the grating ruler, along with negative pressure dust removal. However, when the worktable's own mass and moving speed are mismatched, rapid start and stop can cause resonance. Excessive vibration duration can lead to prolonged positioning time and reduced marking efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rapid positioning structure for the worktable of a fiber laser marking machine. It aims to improve the problem in the prior art where the mismatch between the worktable's own mass and its moving speed causes resonance during rapid start-stop, and the prolonged vibration duration leads to extended positioning time and reduced marking efficiency.

When the clamping block is closed, it is inserted into the mounting groove. Then, the clamping block is opened so that the end of the clamping block is locked in the inner wall of the mounting groove, forming a stable connection. The operation is convenient and it is easy to install and replace the detector. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a rapid positioning structure for the worktable of a fiber laser marking machine, comprising a body 1, with fixing mechanisms 4 installed on both the left and right sides of the top wall of the body 1 for fixing components. A support column 2 is fixedly connected to the left side of the top wall of the body 1, and a connecting block 3 is installed on the upper middle part of the outer wall of the support column 2. An installation mechanism 5 is installed on the right side of the outer wall of the connecting block 3 for facilitating the installation and disassembly of components. The fixing mechanism 4 includes a limiting block 403, which is fixedly connected to the left and right sides of the inner wall of the body 1. Multiple fixing blocks 402 are fixedly connected at equal intervals on the upper middle part of the inner wall of the limiting block 403. A clamping plate 401 is fixedly connected to the end of the fixing block 402, and the inner wall of the fixing block 402 slides. A rack 404 is connected; a clamping plate 405 is fixedly connected to the front end of the rack 404; a sliding groove 406 is provided on the left and right sides of the outer wall of the clamping plate 405; a fixing block 402 is slidably connected to the inner wall of the sliding groove 406; a drive assembly 407 is installed inside the limiting block 403; the drive assembly 407 includes a motor 4072; the motor 4072 is fixedly connected to the left side of the inner wall of the body 1; a gear 4071 is fixedly connected to the output end of the motor 4072; the gear 4071 is rotatably connected to the lower middle part of the inner wall of the limiting block 403; a rotating shaft 408 is fixedly connected to the right end of the gear 4071; another gear 4071 is fixedly connected to the end of the rotating shaft 408; both gears 4071 are meshed with the rack 404.

[0032] Specifically, the inner wall of the limiting block 403 has a gear 4071, and the right end of the gear 4071 is equipped with a rotating shaft 408. The right end of the rotating shaft 408 has another gear 4071. After the motor 4072 starts, it drives the gear 4071 to rotate, thereby driving the two gears 4071 to rotate synchronously. After the gear 4071 rotates, it drives the rack 404, causing the rack 404 to slide back and forth on the inner wall of the fixed block 402. At the same time as the rack 404 slides, the fixed block 402 also slides on the inner wall of the slide groove 406 to prevent the rack 404 from falling off and becoming misaligned. This allows the clamping plate 2 405 to move closer to the clamping plate 1 401, fixing the detection table 7 that slides on the outer wall of the slide rail 6, preventing the detection table 7 from having a slight displacement during equipment operation, which would affect the marking accuracy.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The installation mechanism 5 includes a fixing frame 501, which is fixedly connected to the right side of the outer wall of the connecting block 3. Multiple clamping blocks 505 are equidistantly slidably connected to the inner bottom wall of the fixing frame 501. A mounting block 507 is provided at the bottom of each clamping block 505. Multiple mounting grooves 506 are equidistantly opened on the top wall of each mounting block 507. A detector 508 is fixedly connected to the bottom of each mounting groove 506. The clamping blocks 505 are slidably connected to the inner wall of the mounting groove 506. A transmission assembly 502 is installed in the upper middle part of the inner wall of the fixing frame 501. The transmission assembly 502 includes an electric push rod. 5021, an electric push rod 5021 is fixedly connected to the upper part of the inner wall of the fixed frame 501. The output end of the electric push rod 5021 is fixedly connected to a connecting rod 5022. The front and rear sides of the outer wall of the connecting rod 5022 are slidably connected to sliders 5023. The left side of the outer wall of the slider 5023 is rotatably connected to a crank 504. The end of the crank 504 is rotatably connected to the left side of the outer wall of the fixed frame 501. The right side of the outer wall of the slider 5023 is rotatably connected to a crank 503. The end of the crank 503 is rotatably connected to the rear side of the outer wall of the clamping block 505.

[0034] Specifically, the electric push rod 5021 is activated, which pulls the connecting rod 5022, causing the connecting rod 5022 to move up and down on the inner wall of the fixed frame 501. The up and down movement of the connecting rod 5022 causes the sliders 5023 on both sides of its outer wall to slide simultaneously. The sliders 5023 slide to drive the crank 503, which in turn drives the clamping block 505, so that the clamping block 505 can also open and close simultaneously on the bottom of the inner wall of the fixed frame 501. When the clamping block 505 is closed, it is inserted into the mounting groove 506. Then the clamping block 505 is opened so that the end of the clamping block 505 is locked in the inner wall of the mounting groove 506, forming a stable connection. The operation is convenient and it is easy to install and replace the detector 508.

[0035] Reference Figure 1 , Figure 2 and Figure 3Multiple slide rails 6 are fixedly connected to the front and rear sides of the top wall of the machine body 1, and a detection table 7 is slidably connected to the outer wall of the slide rails 6; a controller 8 is installed on the right side of the outer wall of the machine body 1, and a display 9 is fixedly connected to the right side of the top wall of the controller 8.

[0036] Specifically, the testing platform 7 slides on the outer wall of the slide rail 6 for easy operation. The controller 8 can receive signals transmitted from sensors in various parts of the equipment and analyze and process these signals according to the preset program logic to realize the automated operation of the spin-drying. The display 9 can display various information collected by the controller 8 in real time, and the operator can clearly understand the key data of the current operation of the equipment through the display 9.

[0037] Working principle: A gear 4071 is located on the inner wall of the limiting block 403, and a rotating shaft 408 is located at the right end of the gear 4071. Another set of gears 4071 is also installed on the right end of the rotating shaft 408, forming a symmetrical structure with the gear 4071 on the left. When the motor 4072 starts working, it drives the gear 4071 on the left to rotate. The gear 4071 on the right will also rotate synchronously. This synchronous rotation mechanism ensures that the two gears 4071 can rotate at the same speed and direction, thus achieving precise transmission. As the gears 4071 rotate, they drive the rack 404 for transmission. The rack 404 slides back and forth along the inner wall of the fixed block 402, while the fixed block 402 also slides on the inner wall of the groove 406. This design is to prevent the rack 404 from falling off or misaligning during movement, ensuring the stability of its movement. As the rack 404 slides, the second clamping plate 405 gradually moves towards the first clamping plate 401, thereby effectively fixing the inspection table 7 sliding on the outer wall of the slide rail 6. This fixing measure is to prevent the inspection table 7 from undergoing slight displacement during equipment operation, thus ensuring that the marking accuracy is not affected.

[0038] After the electric push rod 5021 is activated, it pulls the connecting rod 5022, causing the connecting rod 5022 to move up and down on the inner wall of the fixing frame 501. The up and down movement of the connecting rod 5022 drives the sliders 5023 on both sides of its outer wall to slide synchronously. The sliding of the sliders 5023 further drives the crank 503, which in turn transmits power to the clamping block 505. The clamping block 505 opens and closes at the bottom of the inner wall of the fixing frame 501 to achieve its function. When the clamping block 505 is closed, it inserts into the mounting slot 506 to ensure a clamping effect; when the clamping block 505 is open, its end is locked onto the inner wall of the mounting slot 506, forming a stable connection. This design not only improves the convenience of operation but also facilitates the installation and replacement of the detector 508, making the whole process more efficient and flexible.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
