Description

Technical Field

[0001] This utility model relates to the field of optomechanical technology, and in particular to a high-precision optomechanic. Background Technology

[0002] Three-axis optomechanical automation equipment is widely used in precision operations such as dispensing, assembly, and testing in the 3C electronics industry. As the core support platform carrying various actuators, the structure design of the optomechanical system directly determines the stability, accuracy, and functional expansion capabilities of the entire machine. In practical applications, optomechanical systems are usually highly versatile. By loading different dedicated function modules and matching control programs, they can be quickly converted into automated equipment for specific purposes. For example, after assembling the dispensing mechanism and control software, an automatic dispensing machine can be formed. This modular design greatly improves the flexibility and adaptability of the equipment, and therefore it is widely used in the field of electronics manufacturing.

[0003] Currently, the optomechanical equipment commonly used in the industry has a relatively standardized overall structure. A typical form is as follows: a square tube welded structure is used as the basic frame, on which a steel plate or marble substrate is installed as the platform support surface. The crossbeam is made of aluminum alloy or marble to support the X-axis motion mechanism. Steel as the substrate has sufficient strength, but the overall precision is low and it is susceptible to thermal expansion and contraction and mechanical vibration. Marble as the substrate is suitable for high-precision applications, but the material itself is relatively fragile and easily damaged during processing and transportation. At the same time, it is more expensive and heavier, which is not conducive to the overall lightweighting and high dynamic response of the equipment. It is difficult to meet the comprehensive requirements of the current 3C electronics manufacturing industry for high precision, high speed, modularity and low cost of equipment.

[0004] Therefore, a high-precision optical engine is proposed to solve the above problems. Utility Model Content

[0043] Reference Figures 1 to 5 This utility model discloses a high-precision optical engine, comprising:

[0044] The rack 100 includes a support platform 110 and a work platform 120;

[0045] A carbon fiber crossbeam 200 is slidably mounted on the work platform 120, and a mounting base 210 is slidably mounted on the crossbeam;

[0046] The motion module includes an X-axis motion module 300 and a Y-axis motion module 400. The X-axis motion module 300 is mounted on the carbon fiber crossbeam 200, and the Y-axis motion module 400 is slidably mounted on the work platform 120.

[0047] Mounting base 210 is slidably mounted on the X-axis motion module 300 and has several positioning holes 220;

[0048] The functional module 500 is detachably connected to the mounting base 210 through the positioning hole 220;

[0049] The support platform 110 and the working platform 120 are integrally formed. The functional module 500 reciprocates along the opening direction of the carbon fiber crossbeam 200 through the X-axis motion module 300, and the carbon fiber crossbeam 200 reciprocates along the extension direction of the working platform 120 through the Y-axis motion module 400.

[0050] This invention provides a high-precision optomechanic, aiming to solve the problems of insufficient structural stability, limited motion accuracy, and poor module compatibility of existing optomechanics. To this end, the solution adopts an integrated molding method for the support platform 110 and the working platform 120 to improve the overall structural rigidity and geometric stability. In terms of functional components, a carbon fiber crossbeam 200 is introduced to cooperate with a dual-axis motion module to achieve lightweight and high-precision two-dimensional motion control. In terms of installation, a sliding mounting base 210 is provided, and it is detachably connected to the functional module 500 through several positioning holes 220 to enhance the system's flexible configuration capability.

[0051] The overall structure constructs a bidirectional motion path along the X and Y axes. Through the combined control of the X-axis motion module 300 and the Y-axis motion module 400, the functional module 500 can achieve high-precision positioning and operation in a two-dimensional plane, meeting the needs of various optical processing, inspection, or assembly tasks. Specifically, the frame 100 includes a support platform 110 and a work platform 120, which are integrally formed. The work platform 120 is used to support the motion components, and the support platform 110 is used for overall structural support and stability. The carbon fiber crossbeam 200 is slidably mounted on the work platform 120 and can move along the Y-axis direction to carry the X-axis motion components. The material is carbon fiber to reduce errors caused by weight and thermal expansion. The X-axis motion module 300 is mounted on the carbon fiber crossbeam 200; the Y-axis motion module 400 is slidably mounted on... On the work platform 120, a crossbeam is driven to move along the Y-axis. The mounting base 210 is slidably mounted on the X-axis motion module 300 to support the functional module 500. Several positioning holes 220 are provided for the precise installation of the functional module 500. The functional module 500 is detachably connected to the mounting base 210 through the positioning holes 220 and can be replaced with different types of functional units (such as lasers, probes, cameras, etc.) according to usage requirements. During operation, the Y-axis motion module 400 drives the carbon fiber crossbeam 200 to move along the extension direction (i.e., the Y-direction) of the work platform 120, and the X-axis motion module 300 drives the mounting base 210 and the functional module 500 to move along the extension direction (i.e., the X-direction) of the crossbeam, thereby enabling the functional module 500 to perform high-precision two-dimensional positioning operations throughout the entire working area.

[0052] In this embodiment, the optomechanical frame 100 is made of mineral casting, and the frame 100 and the substrate are integrally molded. This structurally avoids assembly errors between the support platform 110 and the working platform 120 in traditional splicing structures, improving the overall structural stability and machining accuracy. After precision machining, the main precision surfaces of the mineral casting frame 100 can achieve a machining accuracy of 5μm, and the overall flatness can be controlled within 10μm, which meets the application requirements of most high-precision electronic devices. The mineral casting material has the following characteristics: density approximately 2.4 g / cm³. 3 With a tensile strength of approximately 15 MPa, a compressive strength of approximately 150 MPa, an elastic modulus of 31 GPa, a coefficient of thermal expansion of 2.0 × 10^-6 / ℃, and a damping coefficient as high as 0.16, this material has excellent vibration absorption properties and can effectively absorb mechanical vibrations caused by external disturbances or high-speed motion of linear motors, thereby ensuring the stability and repeatability of the system during operation.

[0053] This embodiment significantly improves the overall precision and stability of the structure through the design of the frame 100, which is integrally formed by mineral casting. The mineral material itself has high damping characteristics, which can effectively absorb external impacts and micro-vibrations caused by motor movement, avoid the resonance effect caused by excessive rigidity of traditional steel frames, and ensure the stability and high repeatability of the system during operation.

[0054] The frame 100 has a hollow shape;

[0055] The carbon fiber crossbeam 200 has a hollow structure 600, which is arranged along the opening direction of the carbon fiber crossbeam 200.

[0056] In this embodiment, the frame 100 adopts a hollow structure 600 to effectively reduce the overall weight of the machine and the load-bearing pressure on the installation ground. It also facilitates the layout of internal pipelines and functional components, improving maintainability and modular expandability. Since the mineral casting itself possesses good damping characteristics, it maintains sufficient rigidity even after the hollow design, without affecting overall stability. Secondly, the crossbeams have symmetrically arranged hollow structures 600, providing good structural balance and reducing vibration and sway caused by asymmetrical inertia during high-speed operation, thus improving the stability of the linear motion system. The introduction of high-damping carbon fiber material gives the crossbeams extremely high strength and rigidity while providing excellent vibration absorption and damping capabilities, effectively suppressing vibration responses caused by high-speed movement and improving processing accuracy and repeatability. Simultaneously, the carbon fiber crossbeam 200 has a significantly lower mass than metal or marble materials, effectively reducing the inertial burden on the drive system and allowing the motor thrust to be converted into speed and acceleration more efficiently.

[0057] The crossbeam is provided with diagonal braces 230 on both sides along its length, which are connected to the Y-axis motion module 400, and the diagonal braces 230 are triangular in shape.

[0058] During equipment operation, the carbon fiber crossbeam 200 is subjected to complex forces from the driving direction and vertical direction as the functional module 500 moves. Especially under high-speed movement or load shift, it is prone to deformation such as lateral torsion or vertical sinking. By setting triangular diagonal braces 230 symmetrically distributed on both sides of the crossbeam, the diagonal component force can be effectively decomposed, realizing the closure and dispersion of forces, avoiding local stress concentration, and forming a stable spatial support frame. Under dynamic loading conditions, this structure can effectively improve the overall bending stiffness and stability of the crossbeam and suppress deformation.

[0059] The working platform 120 is provided with limit blocks 130, which are located at both ends of the Y-axis motion module 400 and are configured to limit the movement stroke of the Y-axis motion module 400.

[0060] The limit block 130 is designed to limit the maximum sliding stroke of the Y-axis motion module 400 along the work platform 120. When mounted without being driven or returning to the initial state, the limit block 130 is in contact with the side of its inclined support 230. This contact method forms a triangular stable structure geometrically, making the stopping point more impact resistant. The setting of the limit block 130 provides a physical limit protection mechanism, which can effectively prevent overtravel caused by program abnormalities, misoperation or drive failure, and avoid problems such as structural collision, component damage or system malfunction.

[0061] The working platform 120 is equipped with displacement sensors 700 at both ends along the movement direction of the Y-axis motion module 400, and is connected to the Y-axis motion module 400.

[0062] The Y-axis motion module 400 has two displacement sensors 700 on the side near its initial end and one displacement sensor 700 on the side near its end of motion.

[0063] The working platform 120 is also provided with a track 800 for the displacement sensor 700 to slide along the track 800 to change its position.

[0064] Based on the above embodiments, in order to achieve real-time position detection and precise motion control of the Y-axis motion module 400, this technical solution provides multiple displacement sensors 700 at both ends of the working platform 120 along the motion direction of the Y-axis motion module 400 and electrically connects them to the Y-axis motion module 400. Specifically, two sensors are set on the side closer to the initial end of the Y-axis motion module 400, and one sensor is set on the side closer to its end of motion. Through asymmetrical distribution, the comprehensive functions of position judgment, correction control and stroke limit are realized under different motion states.

[0065] This design embodies a control strategy that integrates multi-point sensing and distributed detection, balancing measurement accuracy and system safety. During equipment operation, the Y-axis motion module 400 reciprocates on its track 800. Displacement sensors 700, located at both ends of its motion path, sense the module's position. Two sensors at the initial end enable high-precision identification and dual redundancy verification of the initial position, providing high-stability triggering during system power-on self-test and zero-point reset. They also provide multi-level precision reference points during the initial stage of motion, reducing offset errors. A sensor at the end determines whether the motion has reached the end-point critical position, serving as a limit alarm and stop signal trigger for protection, reducing the risk of end-point collisions and extending system lifespan.

[0066] The displacement sensor 700 is connected to the Y-axis motion module 400. By sensing the current position of the module, it provides real-time position data to the control system, thereby achieving dynamic position feedback and path correction, which helps the entire optomechanical system achieve precise Y-axis motion control. Compared with the traditional method of setting only a single sensor at the end or using encoder control, the design of this embodiment improves the initial positioning accuracy and stability. Setting two sensors at the initial end can realize dual-point verification and fault tolerance, which is particularly suitable for the initial reset of the equipment after power-on or the origin return operation after long-term operation, avoiding misjudgment or missed steps. Setting a sensor at the end can detect the limit position status in time, and combined with the limit logic, realize emergency braking or alarm processing during the motion process to prevent collision or overtravel failure. Through the redundant arrangement of sensors, it can support the switching of different motion strategies in high-speed and precision modes, so that the system can balance efficiency and accuracy.

[0067] In summary, this technical solution achieves high-precision initial positioning, multi-point position information sensing, and end-effector protection for the Y-axis motion module 400 by setting two displacement sensors 700 at the initial end and one displacement sensor 700 at the end. This improves the system's positioning accuracy, motion stability, and operational safety, while also providing good control flexibility and system scalability, making it suitable for the two-dimensional motion control requirements of high-precision optical systems.
