Description

Technical Field

[0001] This utility model relates to the field of laser motor technology, and specifically to a spring sheet and a laser motor mirror fixing structure. Background Technology

[0002] The laser motor is a crucial component in a laser printer, primarily used for precisely controlling the laser scanning system.

[0003] The following problems exist in the current market: the spring of the existing laser motor relies on the elastic deformation generated by the overall force, which results in a large deformation of the mirror after the spring is assembled with the mirror, and a large change in the flatness of the mirror.

[0004] The technical problem to be solved by this utility model is to provide a spring and laser motor mirror fixing structure, so that the deformation of the mirror is small and the change in the flatness of the mirror is small after the spring and the mirror are assembled. Utility Model Content

[0005] The technical problem this invention addresses is: the main body of the spring sheet is a dome-shaped structure with several equally spaced through slots running through it. On one hand, the presence of these slots gives the spring sheet a certain degree of flexibility and deformability in its overall structure. On the other hand, the elastic deformation rods formed between adjacent slots are the key component for the spring sheet to achieve its elastic function. When subjected to external force, these elastic deformation rods can cause the spring sheet to deform by pressing them. The equally spaced through slots and elastic deformation rods ensure that the spring sheet maintains a relatively uniform stress distribution during deformation, reducing the risk of damage caused by localized stress concentration, extending the service life of the spring sheet, and thus improving the overall reliability and stability of the laser motor. Due to the deformation generated by the elastic deformation rods, the deformation of the mirror surface is small after the spring sheet is assembled with the mirror, resulting in minimal change in the mirror's flatness.

[0006] A spring sheet includes a spring sheet body, characterized in that the spring sheet body is generally shaped like a dome; and a mounting hole is formed through the center of the spring sheet body; and a plurality of through slots are formed through the spring sheet body and arranged at equal intervals around it; and an elastic deformation rod is formed between adjacent through slots; the spring sheet is deformed by pressing the elastic deformation rod.

[0007] Preferably, the through groove is an isosceles trapezoid.

[0008] A laser motor mirror fixing structure includes a mirror and a spring, and also includes a mounting platform for placing the mirror; the mounting platform has a central axis vertically positioned at its center; and the spring is installed with the central axis, fixing the mirror on the mounting platform.

[0009] Preferably, the bottom of the mounting platform is provided with a mounting sleeve that fits therein; and the top of the mounting sleeve is formed with a through mounting hole; and the bottom of the mounting platform fits into the mounting hole; and a number of auxiliary grooves for fitting are formed at equal intervals around the outer edge of the mounting hole.

[0010] Preferably, the mounting sleeve has a ring magnet inside.

[0011] Preferably, the mounting hole of the spring contacts is fitted with the cylindrical protrusion; and the bottom of the spring contacts abuts against the top of the mirror surface.

[0012] Preferably, the mirror is a four-sided lens.

[0013] Preferably, the top of the mounting platform is formed with a cylindrical protrusion; and a mirror positioning hole is formed through the center of the mirror surface; and the mirror positioning hole is sleeved with the cylindrical protrusion.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The spring sheet and laser motor mirror fixing structure of this utility model have a spring sheet body that is generally dome-shaped with several through slots arranged at equal intervals around the spring sheet body. On the one hand, the existence of through slots gives the spring sheet a certain degree of flexibility and deformability in its overall structure. On the other hand, the elastic deformation rods formed between adjacent through slots are the key part of the spring sheet to realize its elastic function. When these elastic deformation rods are subjected to external force, pressing them can cause the spring sheet to deform. The equally spaced through slots and elastic deformation rods enable the spring sheet to maintain a relatively uniform stress distribution during deformation, reduce the risk of spring sheet damage caused by local stress concentration, extend the service life of the spring sheet, and thus improve the overall reliability and stability of the laser motor.

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] It should be noted that the terms "first," "second," etc., used in this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with this disclosure.

[0025] Please see Figures 1-5 In this embodiment of the utility model, a spring sheet includes a spring sheet body 1; the spring sheet body 1 is generally in the shape of a dome; and the center of the spring sheet body 1 is formed with a mounting hole 2; and the spring sheet body 1 is formed with a plurality of through grooves 3 arranged around it at equal intervals; and an elastic deformation rod 4 is formed between adjacent through grooves 3; the spring sheet is deformed by pressing the elastic deformation rod 4.

[0026] Specifically, the main body 1 of the spring is generally dome-shaped. This shape provides a relatively stable and adaptable basic form for it in the laser motor, allowing it to better cooperate with other components and adapt to the internal spatial layout of the laser motor. The mounting hole 2 formed through the center of the main body 1 is an important structure for achieving precise installation and positioning of the spring and other key components of the laser motor. Through this mounting hole 2, the spring can be firmly fixed in the corresponding position, ensuring that the spring will not shift during the operation of the laser motor, thereby ensuring the stability of the entire system. Several through slots 3 are formed through the main body 1 and are arranged at equal intervals around it. On the one hand, the existence of through slots 3 gives the spring a certain degree of flexibility and deformability in its overall structure; on the other hand, adjacent... The elastic deformation rods 4 formed between the through slots 3 are the key part for the elastic function of the spring sheet. When these elastic deformation rods 4 are subjected to external forces, such as by pressing them, the spring sheet can deform. This elastic deformation capability is crucial for laser motors. It can absorb and buffer the vibration and impact forces generated during the operation of the laser motor to a certain extent, avoiding damage to the core components of the laser motor. It also helps to maintain the stability and accuracy of laser output. Moreover, the equally spaced through slots 3 and elastic deformation rods 4 enable the spring sheet to maintain a relatively uniform stress distribution during deformation, reducing the risk of spring sheet damage caused by local stress concentration, extending the service life of the spring sheet, and thus improving the overall reliability and stability of the laser motor.

[0027] Furthermore, the through groove 3 is an isosceles trapezoid.

[0028] Specifically, the grooves 3 that surround and are evenly spaced on the main body 1 of the spring are designed in the shape of isosceles trapezoids. The isosceles trapezoidal grooves 3 give the spring structure greater flexibility and deformability. The elastic deformation rods 4 formed between the grooves 3 are the core components for the spring to perform its elastic function. When pressure is applied to the elastic deformation rods 4, the spring can produce corresponding deformation. The isosceles trapezoidal grooves 3 are designed to help guide stress transmission and distribution more rationally during the deformation process of the spring. Compared with other shapes, the isosceles trapezoidal grooves 3 allow the stress to be more evenly distributed along the hypotenuse and base of the trapezoid when the spring is under force, reducing the phenomenon of local stress concentration. This not only reduces the probability of the spring being damaged due to excessive local stress and extends the service life of the spring, but also ensures the consistency of the spring's performance during multiple deformation processes.

[0029] A laser motor mirror fixing structure includes a mirror 8 and a spring, and a mounting platform 5 for placing the mirror 8; a central shaft 6 is vertically provided at the center of the mounting platform 5; and the spring is installed with the central shaft 6, and the spring fixes the mirror 8 on the mounting platform 5.

[0030] Specifically, the components include a mirror 8, a specially designed spring, and a mounting platform 5 for placing the mirror 8. The mounting platform 5 serves as the base for placing the mirror 8, providing a stable support platform. The central shaft 6 is vertically positioned at the center of the mounting platform 5, providing a precise positioning reference for the installation of the spring, ensuring that the spring can be accurately installed in the appropriate position and thus guaranteeing the installation accuracy of the entire fixing structure. The spring connects the central shaft 6 and the mirror 8 and performs the fixing function. The spring is generally dome-shaped, and the central mounting hole 2 can be smoothly fitted onto the central shaft 6, achieving a stable installation of the spring and the central shaft 6. The isosceles trapezoidal through slots 3 arranged at equal intervals around the spring, and the resulting elastic deformation rod 4, give the spring good elastic deformation capability. When the spring is installed on the central shaft 6 and the mirror 8 is fixed, the elastic deformation rod 4 can, to a certain extent... The elastic deformation of the spring plate adapts to minute positional changes and orientation adjustments of the mirror 8, providing appropriate clamping force to ensure that the mirror 8 is stably fixed on the mounting stage 5. Compared with rigid fixing, this elastic fixing method can better buffer and absorb external vibrations and impacts, avoiding direct external forces acting on the mirror 8 and reducing the risk of displacement or damage to the mirror 8 due to impacts. This ensures the positional accuracy and optical performance of the mirror 8 in the laser motor. As an important optical component in the laser motor, the stable fixing of the mirror 8 is crucial for laser transmission and focusing functions. Through the cooperation of the spring plate with the mounting stage 5 and the central shaft 6, the mirror 8 can be reliably fixed in the predetermined position, ensuring that the laser can perform optical operations such as reflection and refraction as designed when passing through the mirror 8, thereby ensuring the normal operation and output performance stability of the laser motor.

[0031] Furthermore, the bottom of the mounting platform 5 is provided with a mounting sleeve 7 that fits therein; and the top of the mounting sleeve 7 is formed with a mounting hole 2 through it; and the bottom of the mounting platform 5 fits into the mounting hole 2; and a number of fitting auxiliary grooves 9 are formed at equal intervals around the outer edge of the mounting hole 2.

[0032] Specifically, the mounting platform 5, as the supporting component for the mirror 8, features a design at its bottom that engages with the mounting sleeve 7, further enhancing the stability of the entire fixing structure and the ease of installation. The mounting hole 2, formed through the top of the mounting sleeve 7, provides a precise engagement position for the bottom of the mounting platform 5, allowing it to be accurately installed on the mounting sleeve 7 and ensuring the relative positional accuracy between components. This precise installation is crucial for the normal operation of the laser motor's internal optical system, ensuring that the mirror 8 functions correctly and avoiding problems such as abnormal laser transmission due to installation deviations. Several equally spaced auxiliary grooves 9 surround the outer edge of the mounting hole 2, assisting in positioning and enhancing connection stability during the engagement of the mounting platform 5 and the mounting sleeve 7. During installation, the auxiliary grooves 9 guide the mounting platform 5 to be inserted more smoothly into the mounting hole 2, reducing deviations and resistance during installation and improving installation efficiency. Simultaneously, the equally spaced auxiliary grooves 9 ensure a more uniform connection between the mounting platform 5 and the mounting sleeve 7, dispersing stress generated during installation and preventing loosening or damage caused by localized stress concentration.

[0033] Furthermore, the top of the mounting platform 5 is formed with a cylindrical protrusion 12; and a mirror positioning hole 13 is formed through the center of the mirror 8; and the mirror positioning hole 13 is sleeved with the cylindrical protrusion 12.

[0034] Specifically, the cylindrical protrusion 12 provides a precise positioning reference for the installation of the mirror 8; the mirror positioning hole 13 formed through the center of the mirror 8 can be precisely fitted with the cylindrical protrusion 12; this fitting method can quickly and accurately place the mirror 8 in the correct position on the mounting platform 5 during installation, greatly improving the efficiency and accuracy of installation; at the same time, this tight fitting makes the position of the mirror 8 on the mounting platform 5 more stable, effectively preventing the mirror 8 from shifting in the horizontal direction, and ensuring the positional accuracy of the mirror 8 during the operation of the laser motor.

[0035] Furthermore, the mounting hole 2 of the spring sheet is sleeved with the cylindrical protrusion 12; and the bottom of the spring sheet abuts against the top of the mirror surface 8.

[0036] Specifically, the cylindrical protrusion 12 not only precisely engages with the mirror positioning hole 13 at the center of the mirror 8, achieving the initial positioning of the mirror 8, but also cooperates with the mounting hole 2 at the center of the spring sheet. The engagement of the mounting hole 2 with the cylindrical protrusion 12 allows the spring sheet to be accurately mounted on the mounting platform 5 and ensures the positional stability of the spring sheet during operation. This dual positioning method (both the mirror 8 and the spring sheet are positioned by engaging with the cylindrical protrusion 12) greatly improves the positioning accuracy of the entire fixed structure, ensuring that the mirror 8 and the spring sheet are always in the correct position during the operation of the laser motor, reducing the impact of positional deviation on laser transmission and optical performance.

[0037] Furthermore, mirror 8 is a four-sided mirror.

[0038] Specifically, compared to a regular single mirror, a four-sided mirror has more possibilities in terms of optical function; it can realize laser reflection, refraction and other operations in multiple directions, and the adjustment of the laser optical path and beam control are more complex and precise.

[0039] Furthermore, the interior of the mounting sleeve 7 is equipped with a ring magnet 10.

[0040] Specifically, the presence of the ring magnet 10 provides additional fastening force and positioning assistance for the entire fixing structure; the mounting sleeve 7 and the bottom of the mounting platform 5 are originally fixed by the mounting hole 2 and the sleeve auxiliary groove 9, but the magnetic force of the ring magnet 10 can make the connection between the mounting platform 5 and the mounting sleeve 7 tighter; when the mounting platform 5 is installed on the mounting sleeve 7, the attraction force generated by the ring magnet 10 will ensure that the relative position between the two is more stable, reducing the risk of loosening caused by factors such as vibration.
