[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] It is understandable that, referring to Figures 1 to 5 In an embodiment of the first aspect of the present invention, a laser printing assembly is provided, which is applied to a printer and has multiple adjustment capabilities, thereby helping to improve printing quality.

[0037] The laser printing assembly mainly includes a base plate 100, a first mounting frame 200, a second mounting frame 300 and a laser 400. The base plate 100 serves as the foundation of the entire assembly. The first mounting frame 200 is connected to the base plate 100, the second mounting frame 300 is connected to the first mounting frame 200, and the laser 400 is installed on the second mounting frame 300. Corresponding to the laser emitting position of the laser 400, the first mounting frame 200 and the second mounting frame 300 are provided with openings for laser emission. Vertical support plates 110 are provided at both ends of the base plate 100. The support plates 110 not only play a supporting role, but also have a parallel adjustment mechanism on the support plates 110. The relative angle between the laser printing assembly and the printed object can be adjusted by the parallel adjustment mechanism. The parallel adjustment mechanism includes a first arc groove 101 and a fastener 102. The fastener 102 is inserted into the first arc groove 101. Figure 1 and Figure 6As shown, the first arcuate groove 101 can be provided on the support plate 110 or on the printer frame 500. By adjusting the position of the fastener 102 in the arcuate groove, the levelness of the base plate 100 can be fine-tuned, thereby adjusting the parallelism between the laser 400 and the printed object, which is important for improving printing quality. The fastener 102 can be a bolt, and tightening the bolt locks the base plate 100 to ensure printing stability.

[0038] The first mounting frame 200 is provided with a vertical first upright plate 210, which is provided with a vertically arranged first strip groove 211. The second mounting frame 300 is provided with a first guide pin 310, which is inserted into the first strip groove 211, allowing the second mounting frame 300 to move up and down along the strip groove, providing guidance for the elevation adjustment of the laser 400. A vertical adjustment screw 120 is connected to the base plate 100, with the upper end of the adjustment screw 120 abutting the second mounting frame 300. By turning the adjustment screw 120, the laser 400 and the second mounting frame 300 can be moved up and down, thereby adjusting the printing distance of the laser 400 to accommodate different materials and specifications of printed materials. It is understood that the adjustment screw 120 can be installed in a threaded hole in the base plate 100 or the first mounting frame 200, or a nut can be welded to the base plate 100 or the first mounting frame 200, and the adjustment screw 120 can be installed in the nut, either of which can meet the requirements of use.

[0039] The laser printing assembly features parallelism adjustment: a parallelism adjustment mechanism adjusts the relative angle between the base plate 100 and the printer frame 500, ensuring parallelism between the laser 400 and the printed object. This adjustment capability is crucial for maintaining the clarity and accuracy of printed images, especially during high-precision printing, where even the slightest angular deviation can degrade print quality. The laser printing assembly also features print distance adjustment: by turning the adjustment screw 120, the laser 400 and second mounting bracket 300 can be raised or lowered, adjusting the laser 400's printing distance.

[0040] The design of this laser printing assembly has a number of advantages, including: 1. Improved printing quality: By precisely adjusting the parallelism and printing distance between the laser 400 and the printed object, the printing quality is significantly improved, and it is particularly suitable for high-precision printing. 2. Strong versatility: It can adapt to printing materials of different thicknesses, making the application range of laser printers even wider. 3. Easy to operate: Through simple mechanical adjustments, the laser printer can be precisely adjusted without the need for complex electronic controls, reducing production difficulty and costs. 4. High stability: The connection between the various components is firm, ensuring the stability of the laser printer during long-term operation. 5. Easy maintenance: Due to the modular design, the various components are easy to disassemble and replace, which facilitates daily maintenance and repairs.

[0041] It will be appreciated that in some embodiments of the present invention, the base plate 100 and the two support plates 110 are integrally formed sheet metal parts, and the first mounting bracket 200 and the second mounting bracket 300 are also sheet metal parts. The integrated sheet metal parts not only improve the structural stability of the assembly, but also enhance its durability and manufacturing efficiency. The manufacture of sheet metal parts generally uses punching technology, which can quickly and accurately cut the desired shape from the metal sheet, while producing clean, smooth edges and reducing the need for subsequent processing. The first mounting bracket 200 and the second mounting bracket 300 are also made of sheet metal parts, which not only ensures structural consistency, but also facilitates large-scale production and reduces production costs.

[0042] Reference Figure 1 In some embodiments of the present invention, both support plates 110 are provided with a parallel adjustment mechanism, which includes two first arcuate grooves 101 and a circular hole 103, and the first arcuate grooves 101 and the circular hole 103 are concentrically arranged. The two first arcuate grooves 101 and the circular hole 103 can be provided on the support plate 110, and the printer frame 500 is provided with a rotating shaft 501, which passes through the circular hole 103 and provides support and a rotation fulcrum. The first arcuate groove 101 and the fastener 102 cooperate as a guide, and the fastener 102 has a locking function. For example, the fastener 102 is a bolt, which is fitted with a nut and locked by tightening the nut.

[0043] By providing identical parallel adjustment mechanisms on both support plates 110, symmetrical adjustment and more stable support can be achieved, helping to maintain the stability of the laser printing assembly. During the manufacturing process, considering the high precision requirements of the two first arcuate grooves 101 and the circular hole 103, laser cutting technology can be used to precisely cut the two first arcuate grooves 101 and the circular hole 103 on the support plate 110. Subsequently, a three-dimensional support plate 110 structure can be formed through processes such as bending.

[0044] Reference Figure 4 and Figure 5 In some embodiments of the present invention, the laser printing assembly is also designed with a rotation function. A second guide pin 220 is provided on the bottom surface of the first mounting bracket 200, and a second arc-shaped groove 104 is provided on the bottom plate 100. The second guide pin 220 is inserted into the second arc-shaped groove 104. The cooperation between the second guide pin 220 and the second arc-shaped groove 104 enables the rotation of the laser 400, thereby adjusting the direction of the laser 400, achieving more precise control, and improving printing quality.

[0045] Furthermore, four second arcuate slots 104 can be provided on the base plate 100. The four second arcuate slots 104 are concentrically arranged, with their centers located outside the area enclosed by the four second arcuate slots 104. In other words, the rotation axis of the laser 400 is positioned at one end of the first mounting bracket 200. Of course, the center can also be positioned within the area enclosed by the four second arcuate slots 104 to similarly achieve rotation of the laser 400. By arranging the four second arcuate slots 104 concentrically, the operator can adjust the position of the second guide pin 220 within the second arcuate slots 104 as needed to fine-tune the position of the first mounting bracket 200.

[0046] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the second mounting bracket 300 of the laser printing assembly is provided with a third guide pin 320, while the first vertical plate 210 is provided with a third strip groove 212 that mates with the third guide pin 320. The third guide pin 320 and the third strip groove 212 function in conjunction with each other as a sliding and locking mechanism, ensuring the precise positioning of the second mounting bracket 300 on the first mounting bracket 200. The third guide pin 320 can be an annular structure with a smooth outer wall that mates with the third strip groove 212 and an inner hole configured as a threaded hole for mounting a screw. Tightening the screw locks the height of the second mounting bracket 300 and the laser 400, enhancing operational stability.

[0047] The third guide pin 320 cooperates with the third strip groove 212, and the first guide pin 310 cooperates with the first strip groove 211, providing a double guide structure, and using the difference in shape to play a fool-proof role. Figure 5 As shown, further, three third guide pins 320 are provided on the second mounting frame 300, wherein two third guide pins 320 are arranged at one end of the second mounting frame 300, and one third guide pin 320 is arranged at the other end, and a notch for accommodating a third guide pin 320 is provided on the first mounting frame 200. The accuracy of assembly is improved through differentiated structural settings.

[0048] In some embodiments of the present invention, the base plate 100 is connected to two adjustment screws 120, and the lower ends of the two adjustment screws 120 are provided with a plum blossom handle 121. The plum blossom handle 121 provides a convenient operation method, making it easier and more intuitive to adjust the printing distance of the laser 400. By providing the plum blossom handle 121 at the lower ends of the adjustment screws 120, the operator can easily adjust the height of the laser 400 by rotating the handle, thereby adjusting the printing distance, without the need for tools. This not only improves the efficiency of adjustment but also reduces the complexity of operation, making it easy for even non-professionals to quickly get started.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
