Description

Technical Field

[0001] The utility model relates to the technical field of laser marking, and more specifically to an automatic laser marking device for a pallet. Background Art

[0002] Pallet laser marking is a method of marking the surface of a pallet using laser technology. The laser marking machine uses a high-energy laser beam to act on the surface of the pallet, causing the ground state atoms to migrate to a higher energy state and release energy when the atoms return to the ground state, converting light energy into heat energy, thereby forming graphics, text or barcodes on the surface of the pallet.

[0003] In the existing technology, for example, the document with publication number CN219618762U specifically discloses a plastic pallet marking device, in which the pallet can be marked. However, in the loading process, the pallet needs to be manually placed on the workbench and moved so that the pallet marking position is located below the marking machine, so that the pallet marking position can be more accurate. However, this manual operation method is not only time-consuming and labor-intensive, greatly reducing production efficiency, but also due to human fatigue and lack of concentration, it often leads to poor pallet adjustment accuracy, thus affecting the marking effect. To this end, we propose an automatic laser marking device for pallets. Utility Model Content

[0005] The utility model proposes an automatic laser marking device for a pallet, comprising a mounting frame, wherein the bottom of the mounting frame is in a symmetrical structure and is fixedly connected to a support plate, a plurality of electric rollers are fixedly installed on the inner wall of the mounting frame, a connecting hole is opened at the bottom of the inner wall of the mounting frame, a connecting shaft is rotatably connected to the inner wall of the connecting hole, a fixing plate is fixedly connected to the circumferential outer wall of the connecting shaft, and two limit plates are fixedly connected to the circumferential outer wall of the fixing plate in an annular structure with equal spacing.

[0006] Preferably, a second base is fixedly connected to the bottom of the installation frame, a second motor is fixedly connected to the top of the second base, and an output end of the second motor is fixedly connected to the connecting shaft.

[0007] Preferably, a mounting bracket is fixedly connected to the top of the mounting frame, and a laser marking machine is fixedly connected to the top of the mounting bracket.

[0008] Preferably, a plurality of mounting holes are linearly and evenly spaced on both sides of the mounting frame, a connecting plate is provided on both sides of the mounting frame, a plurality of fixing rods are linearly and evenly fixedly connected on the relatively close sides of the two connecting plates, and the ends of the plurality of fixing rods pass through the mounting holes.

[0009] Preferably, the ends of the plurality of fixed rods are fixedly connected to a plurality of connecting frames, and the inner walls of the plurality of connecting frames are rotatably connected to conveying rollers.

[0010] Preferably, a bidirectional threaded rod is rotatably connected to the inner wall of the installation frame, and the first machine base is fixedly connected to both sides of the installation frame. Limiting holes are provided on the tops of the two first machine bases, and fixing plates are fixedly connected to the bottoms of the two connecting plates.

[0011] The beneficial effects of the present invention are:

[0012] 1. The coordinated work of multiple electric rollers can realize the automatic transportation of pallets, greatly improving the convenience of operation and processing efficiency. After the second motor is started, the fixed plate is driven to rotate through the transmission action of the connecting shaft, and multiple limit plates are driven to rotate through the fixed plate. When one of the limit plates flips to the inside of the installation frame, it can accurately block the moving pallet and ensure that the pallet is accurately positioned under the laser marking machine. It not only ensures the accuracy of marking, but also simplifies manual operation, making the pallet movement more convenient and quick, thereby significantly improving the overall processing efficiency.

[0013] 2. When the pallet is accurately positioned under the laser marking machine, the first motor starts immediately, driving the bidirectional threaded rod to rotate. This action enables the two fixed plates to slide smoothly along the limit holes on the first machine base. The movement of the fixed plate drives the movement of the connecting plate. As the fixed rod moves, it can push multiple conveyor rollers to clamp and position the pallet, which not only improves the stability of the pallet during the marking process, but also further improves the accuracy of marking and ensures the marking quality.

A laser marking machine 6 is fixedly connected to the top of the mounting frame 5. The coordinated work of multiple electric rollers 4 can realize the automatic transportation of the pallet, which greatly improves the convenience of operation and processing efficiency. After the second motor 16 is started, the fixed plate 18 is driven to rotate through the transmission action of the connecting shaft 17, and the multiple limit plates 19 are driven to rotate through the fixed plate 18. When one of the limit plates 19 is flipped to the inside of the mounting frame 1, it can accurately block the moving pallet to ensure that the pallet is accurately positioned under the laser marking machine 6, which not only ensures the accuracy of marking, but also simplifies manual operation, making the pallet movement more convenient and quick, thereby significantly improving the overall processing efficiency.

[0020] like Figure 1 and Figure 3As shown, a plurality of mounting holes 3 are linearly and evenly spaced on both sides of the mounting frame 1, and connecting plates 11 are provided on both sides of the mounting frame 1. A plurality of fixing rods 12 are linearly and evenly fixedly connected on one side of the two connecting plates 11 that are relatively close to each other, and ends of the plurality of fixing rods 12 pass through the mounting holes 3, and ends of the plurality of fixing rods 12 are fixedly connected to a plurality of connecting frames 13, and inner walls of the plurality of connecting frames 13 are rotatably connected to conveying rollers 14.

[0021] like Figure 1 and Figure 3 As shown, a bidirectional threaded rod 10 is rotatably connected to the inner wall of the installation frame 1, and first machine bases 7 are fixedly connected to both sides of the installation frame 1. Limiting holes 8 are provided on the tops of the two first machine bases 7, and fixing plates 21 are fixedly connected to the bottoms of the two connecting plates 11. The ends of the two fixing plates 21 pass through the limiting holes 8 and are slidably connected thereto. The two ends of the bidirectional threaded rod 10 pass through the fixing plates 21 and are threadedly connected thereto, and a first motor 9 is fixedly connected to the bottom of one of the first machine bases 7, and the output end of the first motor 9 is fixedly connected to the bidirectional threaded rod 10.

[0022] Working principle: The coordinated work of multiple electric rollers 4 can realize the automatic conveying of the pallet, which greatly improves the convenience of operation and processing efficiency. After the second motor 16 is started, the fixed plate 18 is driven to rotate through the transmission effect of the connecting shaft 17, and the fixed plate 18 drives multiple limit plates 19 to rotate. When one of the limit plates 19 is flipped to the inside of the installation frame 1, it can accurately block the moving pallet to ensure that the pallet is accurately positioned under the laser marking machine 6;

[0023] When the pallet is precisely positioned below the laser marking machine 6, the first motor 9 is immediately started, driving the bidirectional threaded rod 10 to rotate. This action causes the two fixing plates 21 to slide smoothly along the limiting holes 8 on the first machine base 7. The movement of the fixing plates 21 further drives the movement of the connecting plates 11. With the movement of the fixing rods 11, the multiple conveying rollers 14 can be pushed to clamp and position the pallet.

[0024] After the marking is completed, the first motor 9 drives the bidirectional threaded rod 10 to rotate in the opposite direction, so that the multiple conveying rollers 14 on both sides of the pallet gradually break away from the squeeze on the pallet and release the pallet. Then, the second motor 16 drives the fixed plate 18 to rotate in the opposite direction, and the limit plate 19 moves to the inside of the connecting hole 20 to release the obstruction of the pallet. At this time, under the continuous conveyance of the electric roller 4, the pallet is smoothly moved out from under the laser marking machine 6, completing the entire marking process.
