Description

Technical Field

[0001] This utility model relates to the field of steel plate surface marking technology, specifically to an adjustable depth steel plate surface perforation marking device. Background Technology

[0002] Laser marking technology on steel plates uses a high-energy laser beam to create permanent marks on metal surfaces. Its non-contact processing method avoids the physical damage of traditional mechanical marking and the easy detachment of ink-jet marking, significantly improving the accuracy and durability of the markings. This technology is widely used in industries such as automobile manufacturing and electronic components. It not only ensures the immutability of product traceability information but also enhances the aesthetic value of products through color laser marking, becoming a key technology in intelligent manufacturing that combines functionality and economy. To further improve the durability of the marking, laser marking often involves creating a hollowed-out shape on the steel plate, requiring a laser hollowing-out marking machine. Existing laser hollowing-out marking machines mostly consist of a laser and a fixture. During operation, the laser is first focused to improve marking accuracy. Then, the steel plate is placed inside the fixture for fixation, the laser emits laser light, and a three-axis module drives the laser... The laser moves, creating engravings on the steel plate surface. After repeated cycles, a hollowed-out pattern is formed on the steel plate surface, achieving laser marking. Traditional laser marking machines only limit the front-to-back or left-to-right movement of the steel plate when fixing it with a clamp, lacking upper limit. After fixing, the lower end of the steel plate is in close contact with the bottom wall of the clamp, which can easily damage the clamp after the laser penetrates the steel plate. At the same time, as the marking depth increases, the distance between the marking surface of the steel plate and the laser changes. The Z-axis of the three-axis module is needed to ensure that the distance between the marking surface of the steel plate and the laser remains equal, thus ensuring the focusing accuracy of the laser. While the laser moves with the Z-axis, it also moves with the other two axes. The simultaneous movement in three directions generates vibration, which can easily affect the marking accuracy of the laser. Therefore, we propose an adjustable-depth laser marking machine for steel plate surfaces. Utility Model Content

[0003] The technical problem this utility model aims to solve is to overcome the shortcomings of existing technologies and provide an adjustable-depth steel plate surface perforation and coding device. This device not only fixes the steel plate but also creates a limiting effect on the steel plate surface, separating the bottom of the steel plate from the bottom wall of the clamp, reducing the influence of the laser on the clamp. Furthermore, by slowly moving the steel plate, it ensures that the distance between the surface of the steel plate at the coding point and the laser remains equal during the coding process, reducing laser vibration and improving the coding accuracy. This effectively solves the problems in the background technology. The utility model provides the following technical solution: an adjustable-depth steel plate surface perforation and coding device, including a coding base and a clamping mechanism;

[0004] Coding base: It has a base plate on the front side of its upper end, and a liftable clamping plate on the upper end of the base plate;

[0005] The clamping mechanism includes a moving block, a limiting groove, connecting rods, a clamping assembly, and a lifting assembly. The moving blocks are slidably connected to the left and right sides inside the clamping plate. The limiting grooves are all opened inside the moving blocks on the side near the middle of the clamping plate. The connecting rods are rotatably connected to the middle of the clamping plate. The two connecting rods are distributed in a cross state. The left and right sides inside the connecting rods are rotatably connected to guide wheels. The outer surfaces of the guide wheels are slidably connected to the inner walls of the vertically adjacent limiting grooves, providing a foundation for fixing the steel plate. The clamping assembly is set at the upper end of the clamping plate, and the lifting assembly is set between the bottom plate and the clamping plate. While fixing the steel plate, it can also form a limiting effect on the surface of the steel plate and separate the bottom of the steel plate from the bottom wall of the clamp, reducing the influence of the laser on the clamp. It can also ensure that the distance between the surface of the steel plate at the marking point and the laser is always equal during the marking process by slowly moving the steel plate, reducing the vibration of the laser and improving the marking accuracy of the laser.

[0006] Furthermore, the clamping assembly includes clamping blocks, inclined grooves, and universal ball bearings. The clamping blocks are all located at the upper end of the moving block, the inclined grooves are all opened on the side of the clamping block near the middle of the clamping plate, and the universal ball bearings are all located at the upper middle of the clamping plate. This can limit the upper end of the steel plate when fixing it, and also separate the steel plate from the bottom wall of the clamp.

[0007] Furthermore, the clamping mechanism also includes a lead screw and a knob. The lead screw is rotatably connected to the middle of the right side of the clamping plate. The middle of the lower end of the right-side moving block is threadedly connected to the outer surface of the lead screw. The knob is located at the right end of the lead screw, providing a driving effect for fixing the steel plate.

[0008] Furthermore, the lifting assembly includes limiting blocks, limiting grooves, limiting posts, and bidirectional lead screws. The limiting blocks are respectively located at the four lower corners of the clamping plate. The limiting grooves are all opened in the middle of the limiting blocks. The limiting posts are slidably connected to the front and rear sides of the upper part of the base plate. The left and right ends of the limiting posts are provided with limiting heads. The inner walls of the limiting grooves are slidably connected to the outer surfaces of adjacent limiting heads vertically. The bidirectional lead screws are rotatably connected to the middle of the upper part of the base plate. The inner middle of the limiting posts is threadedly connected to the outer surface of the bidirectional lead screws, providing a basis for the slow upward movement of the steel plate.

[0009] Furthermore, the lifting assembly also includes a motor, which is located at the upper front center of the base plate. The input end of the motor is electrically connected to the output end of the microcontroller, and the rear end of the motor's output shaft is fixedly connected to the front end of the bidirectional lead screw, providing a driving effect for the slow upward movement of the steel plate.

[0010] Furthermore, it also includes a two-axis module and a laser. The upper rear end of the marking base is provided with a mounting bracket. The two-axis module is set at the upper end of the mounting bracket. The input end of the two-axis module is electrically connected to the output end of the microcontroller. The laser is set at the lower middle part of the two-axis module. The input end of the laser is electrically connected to the output end of the microcontroller, providing a basis for the movement of the laser.

[0011] Furthermore, it also includes a microcontroller, which is located at the rear right side of the marking base. The input terminal of the microcontroller is electrically connected to an external power supply to provide control for the hollow marking work on the steel plate surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjustable-depth steel plate surface perforation and coding device has the following advantages:

[0013] 1. The support of the universal ball bearing can separate the lower end of the steel plate from the upper end of the clamping plate, reducing the influence of the laser on the bottom wall of the clamping plate. By moving the right moving block, the connecting rod can be driven to deflect outward, and at the same time, the left moving block can be driven to move, thereby creating a limiting effect on the steel plate. Combined with the squeezing of the edge of the steel plate by the inclined groove, the steel plate is fixed and the upper end of the steel plate is also limited.

[0014] 2. The Z-axis movement is lowered to the clamping plate. The rotation of the bidirectional lead screw can drive the two limit posts to move slowly away from the center of the base plate. This causes the outer surface of the limit head to press against the corresponding limit groove, thereby driving the four limit blocks, clamping plate and steel plate to move upward synchronously. This ensures that the depth of the laser marking on the steel plate surface is equal to the height of the clamping plate, which guarantees that the distance between the marking surface of the steel plate and the laser is always equal. This reduces the vibration generated during the laser movement, ensures the laser's focusing accuracy at all times, and improves the marking accuracy of the laser. Attached Figure Description

The laser 7 is a common carbon dioxide laser in the prior art. A carbon dioxide laser is a molecular gas laser that mainly uses carbon dioxide gas as the working substance. The laser 7 is filled with a mixture of CO2, nitrogen, and helium. Through the electrical excitation process of high voltage current, the gas molecules are excited to a high energy state. Subsequently, the molecules transition to a low energy level, releasing photons with a wavelength of 10.6 micrometers.

It also includes a microcontroller 8, which is located at the rear right side of the marking base 1. The input terminal of the microcontroller 8 is electrically connected to an external power supply to provide control for the hollow marking work on the steel plate surface.

[0023] The clamping mechanism 4 includes a movable block 41, a limiting groove 42, a connecting rod 43, a clamping assembly 44, and a lifting assembly 47. The movable block 41 is slidably connected to the left and right sides inside the clamping plate 3. Sliding grooves are provided on the front and rear edges of the upper end of the clamping plate 3. Connecting protrusions are provided on the front and rear edges of the upper end of the movable block 41. A plastic dustproof sheet can be added between the inside of the sliding groove and the vertically adjacent connecting protrusion. The plastic dustproof sheet can contract and expand as the connecting protrusion moves left and right, preventing large particles of impurities from entering the clamping plate 3. The limiting groove 42 is located inside the movable block 41 on one side near the middle of the clamping plate 3. All rods 43 are rotatably connected to the inside of the clamping plate 3. The two connecting rods 43 are distributed in a cross manner. The connecting rod 43 located on the rear right side has a clearance opening in the middle of its interior.

[0024] The clamping assembly 44 is disposed on the upper end of the clamping plate 3. The clamping assembly 44 includes clamping blocks 441, inclined grooves 442 and universal ball bearings 443. The clamping blocks 441 are all disposed on the upper end of the moving block 41. The upper ends of two longitudinally adjacent connecting protrusions are fixedly connected to the lower end of the clamping blocks 441. The inclined grooves 442 are all opened on the side of the clamping blocks 441 near the middle of the clamping plate 3. The universal ball bearings 443 are all disposed on the upper middle part of the clamping plate 3. They can also limit the upper end of the steel plate when fixing the steel plate, and can separate the steel plate from the bottom wall of the clamp. The lifting assembly 47 is disposed between the bottom plate 2 and the clamping plate 3.

[0025] The lifting assembly 47 includes limiting blocks 471, limiting grooves 472, limiting posts 473, and a bidirectional lead screw 474. The limiting blocks 471 are respectively located at the four lower corners of the clamping plate 3. The limiting grooves 472 are all formed in the middle of the interior of the limiting blocks 471. The limiting posts 473 are slidably connected to the front and rear sides of the upper end of the base plate 2. Each end of the limiting post 473 has a limiting head. The inner walls of the limiting grooves 472 are vertically slidably connected to the outer surfaces of adjacent limiting heads. The bidirectional lead screw 474 is rotatably connected to the middle of the upper end of the base plate 2. The inner center of each limiting post 473 is threadedly connected to the outer surface of the bidirectional lead screw 474. The accuracy of 4 is P1 level. A second corrugated tube can be added between the inner wall of the base plate 2 and the limiting post 473. The second corrugated tube is sleeved on the outer surface of the bidirectional lead screw 474. The second corrugated tube can contract and expand as the limiting post 473 moves back and forth, which can protect the bidirectional lead screw 474 from the influence of the external environment and provide a basis for the slow upward movement of the steel plate. The lifting assembly 47 also includes a motor 475. The motor 475 is set in the middle of the front side of the upper end of the base plate 2. The input end of the motor 475 is electrically connected to the output end of the microcontroller 8. The rear end of the output shaft of the motor 475 is fixedly connected to the front end of the bidirectional lead screw 474, providing a driving effect for the slow upward movement of the steel plate.

[0026] To improve the clamping effect, the clamping mechanism 4 also includes a lead screw 45 and a knob 46. The lead screw 45 is rotatably connected to the middle of the right side of the clamping plate 3. The middle of the lower end of the right-side moving block 41 is threadedly connected to the outer surface of the lead screw 45. A corrugated tube is added between the inner wall of the clamping plate 3 and the right-side moving block 41. The corrugated tube is fitted onto the outer surface of the lead screw 45. The corrugated tube will contract and expand as the right-side moving block 41 moves left and right, which can ensure the sealing and lubrication of the lead screw 45. The knob 46 is located at the right end of the lead screw 45, which provides a driving effect for fixing the steel plate. While fixing the steel plate, it can also form a limiting effect on the surface of the steel plate and separate the bottom of the steel plate from the bottom wall of the fixture, reducing the influence of the laser on the fixture. It can also ensure that the distance between the surface of the steel plate at the marking point and the laser 7 is always equal during the marking process by slowly moving the steel plate, reducing the vibration of the laser 7 and improving the marking accuracy of the laser 7.

[0027] The working principle of the adjustable-depth steel plate surface perforation and coding device provided by this utility model is as follows: When performing perforation and coding on the steel plate surface, first fix the steel plate and place it above the universal ball bearing 443. The universal ball bearing 443 provides support for the steel plate and also allows the lower end of the steel plate to separate from the upper end of the clamping plate 3, allowing the steel plate to move freely on the universal ball bearing 443. At this time, rotating the knob 46 drives the lead screw 45 to rotate, and the moving block 41 on the right side moves to the left, driving the clamping block 441 on the right side to move to the left synchronously. At this time, with the movement of the right side... As block 41 moves, the right-side limiting groove 42 presses against the guide wheel, causing the right ends of the two connecting rods 43 to deflect outwards around the pin. Because the middle parts of the two connecting rods 43 are limited by the pin, the left ends of the connecting rods 43 also deflect outwards, driving the guide wheel to press against the limiting groove 42, causing the left-side moving block 41 and clamping block 441 to move to the right. At this time, the two clamping blocks 441 move inwards simultaneously, creating a limiting effect on the steel plate. The inclined groove 442 will create a downward pressing force on the edge of the steel plate, thus also creating a limiting effect on the upper end of the steel plate. Then, the laser 7 is focused. After completion, the microcontroller 8 controls the laser 7 and the two-axis module 6 to work. The laser 7 emits a laser beam that irradiates the surface of the steel plate, while the two-axis module 6 moves the laser 7 along the X and Y axes, causing the laser 7 to form a mark on the steel plate surface. As the laser 7 irradiates, the mark becomes deeper and deeper. To ensure the focusing accuracy of the laser 7, the distance between the marked area on the steel plate and the laser 7 must always be equal. The microcontroller 8 controls the motor 475 to operate, and the output shaft of the motor 475 drives the bidirectional lead screw 474 to rotate. The P1-level bidirectional lead screw 474 can drive... The two limiting posts 473 move slowly to the side away from the center of the base plate 2. As the limiting posts 473 move, the outer surface of the limiting head presses against the corresponding limiting groove 472, thereby driving the four limiting blocks 471 to move upward at the same time. The four corners of the clamping plate 3 also move upward synchronously. During this process, at the same time, the depth of the laser 7 marking the surface of the steel plate is equal to the height of the clamping plate 3 moving upward. This ensures that the distance between the marking surface of the steel plate and the laser 7 is always equal, thereby ensuring the focusing accuracy of the laser 7 at all times and improving the marking accuracy of the laser 7.

[0028] It is worth noting that the microcontroller 8 disclosed in the above embodiments is an STM32F031G4 microcontroller, the motor 475 is a 2BLD10-24GN-20S motor, the two-axis module 6 is an OMDDH02 two-axis module, and the laser 7 is a Vi30 carbon dioxide laser. The microcontroller 8 controls the operation of the motor 475, the two-axis module 6, and the laser 7 using methods commonly used in the prior art.
