Description

Technical Field

[0001] This utility model relates to the field of laser processing equipment technology, and in particular to a laser adjustment mechanism for mass processing of MicroLEDs. Background Technology

[0002] With the development of next-generation display technologies, micro-light-emitting diodes (MicroLEDs) have become a highly anticipated technology due to their advantages such as high brightness, high contrast, and low power consumption. The manufacturing process of MicroLEDs involves the processing, transfer, and repair of massive amounts of micron-sized chips, among which laser processing is one of the key technologies for achieving these processes.

[0003] In specific laser processing applications, the shape of the laser spot often needs to be adjusted according to different processing tasks. For example, when cutting or repairing chips, a square spot may be needed to match the pixel structure, while other processes may require a circular or other custom-shaped spot. Changing the spot shape is usually accomplished by placing light-limiting blocks or masks of different shapes in the laser beam path.

[0004] However, in existing technologies, replacing these light limiters is often inconvenient. Some equipment requires operators to disassemble parts of the laser head using tools for replacement, which is not only cumbersome and time-consuming but also prone to introducing dust contamination or causing errors in optical path realignment during the disassembly and assembly process. This inefficient adjustment method contradicts the high-efficiency and high-flexibility production rhythm required for MicroLED "mass processing." When frequent switching of processing tasks is required, the process of replacing light limiters becomes a significant bottleneck in the production process, seriously affecting the overall processing efficiency.

[0005] Therefore, this utility model proposes a laser adjustment mechanism for mass production of MicroLEDs to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems of cumbersome operation and low replacement efficiency of existing equipment used for MicroLED processing, which makes it difficult to adapt to the high-efficiency and high-flexibility production rhythm, this utility model aims to provide a MicroLED mass processing laser adjustment mechanism with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a laser adjustment mechanism for mass production of MicroLEDs, including: a processing table, a linear motor and a laser head; and a switching mechanism for adjusting the shape of the laser beam.

[0008] The switching mechanism includes a fixed ring, an alignment ring, a bent bar, a slanted buckle block, and a light limiting block.

[0009] Furthermore, the fixing ring surrounds the outer periphery of the laser head and is fixedly connected to the bottom end of the laser head, and the curved strip is fixedly connected to the outside of the fixing ring; the light limiting block is fixedly connected to the bottom end of the alignment ring, and the oblique fastening block is fixedly connected to the outside of the alignment ring; the alignment ring, the fixing ring, the curved strip, and the oblique fastening block are combined in the following way: the alignment ring is attached to the fixing ring by an upward butt joint, and by rotating the alignment ring, the oblique fastening block slides along the outside of the curved strip and engages, thereby realizing that the alignment ring together with the light limiting block fixed thereto is installed below the laser head in a quick-detachable manner.

[0010] Preferably, the processing table is fixed on the linear motor, and the linear motor drives the processing table to achieve high-precision linear reciprocating motion through precise electromagnetic drive, providing a precise positioning basis for laser processing.

[0011] Preferably, it also includes a protective mechanism, which is integrally covered around the processing table and the laser head to isolate external environmental interference and create a stable and clean internal processing space.

[0012] Preferably, as a specific implementation, the protective mechanism includes an outer frame, a frame door, and an L-shaped plate as the connecting bottom end. The outer frame constitutes the main frame of the protective mechanism, the L-shaped plate is fixedly connected to both ends of the outer frame, and the frame door is used to close or open the working opening of the outer frame.

[0013] Preferably, the protective mechanism further includes a protrusion, a hydraulic cylinder, and a connecting block. The protrusion is fixedly connected to the front end of the L-shaped plate, the hydraulic cylinder is rotatably mounted on the protrusion, one end of the connecting block is rotatably connected to the drive end of the hydraulic cylinder, and the other end is fixedly connected to the frame door. The frame door is driven to open and close by the extension and retraction of the hydraulic cylinder, thereby achieving automated control.

[0014] Preferably, in order to enhance connection strength and motion stability, the cross-section of the protrusion is T-shaped, and the cross-section of the connecting block is also T-shaped. This T-shaped cross-section design increases the contact and bearing area, ensuring the reliability of the transmission mechanism under hydraulic drive.

[0015] Preferably, it also includes an auxiliary component disposed between the frame door and the outer frame, which provides additional support and guidance during the rotation and opening of the frame door to ensure smooth and stable movement.

[0016] Preferably, as a specific implementation, the auxiliary component includes a fixed block, a second connecting block, and a rotating rod. The fixed block is fixedly connected to the outside of the frame door, the second connecting block is fixedly connected to the front end of the outer frame, and the two ends of the rotating rod are respectively rotatably connected to the fixed block and the second connecting block, forming a stable linkage structure that effectively assists in the opening and closing of the frame door.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting a switching mechanism consisting of a fixing ring, an alignment ring, a bent strip and an oblique buckle block, uses a rotating buckle to realize the quick installation and replacement of the light limiting block, which solves the problems of complex structure and low replacement efficiency of the existing technology for adjusting the shape of the light spot. It achieves the technical effect of simple structure, convenient operation and quick adaptation to different processing needs.

[0018] 2. This utility model, by setting up a protective mechanism consisting of an outer frame, a frame door, a hydraulic cylinder and auxiliary components, can automatically open and close to form a closed and stable processing space. This solves the problem that the laser processing process is easily interfered with by external environmental factors such as dust and airflow, resulting in poor processing stability. It achieves the technical effect of effectively ensuring the stability of the internal processing environment, thereby improving the consistency and yield of product processing.

[0019] 3. This utility model solves the problem of traditional equipment having scattered functional modules and low integration, which makes it difficult to meet the comprehensive requirements of precision, efficiency and environment for the mass production of MicroLEDs, by integrating the linear motor for precision displacement, the switching mechanism for rapid beam shaping and the protective mechanism for environmental control into an integrated design. It achieves the technical effect of compact structure, complete functions and high degree of automation, providing a reliable guarantee for the high-precision and high-efficiency processing of micron-level devices.

[0022] Example: Reference Figures 1 to 3 This utility model provides a laser adjustment mechanism for mass production of MicroLEDs, which aims to solve the problems in existing MicroLED laser processing equipment where the structure of the spot shape adjustment mechanism is complex or the replacement efficiency is low, and it is difficult to ensure both processing flexibility and micro-environment stability at the same time.

[0023] like Figure 1 and Figure 2 As shown, the MicroLED mass production laser adjustment mechanism includes a processing table 1, a linear motor 2, and a laser head 3. The linear motor 2 drives the processing table 1 to move with high precision. The processing table 1 is fixed on the linear motor 2 and is used to support the chip to be processed. The laser head 3 is located above the processing table 1 and is used to emit a laser beam to process the chip. The mechanism also includes a switching mechanism 4 for adjusting the beam shape of the laser head 3. The switching mechanism 4 is located at the bottom of the laser head 3, and its specific structure is as follows: the switching mechanism 4 includes a fixing ring 41, an alignment ring 43, and a beam limiting block 45. The fixing ring 41 surrounds the outer periphery of the laser head 3 and is fixedly connected to the bottom of the laser head 3. A curved strip 44 is fixedly connected to the outer side of the laser head 3; a beam limiter 45 is used to shape the beam emitted by the laser head 3 to form a beam spot of a specific shape. The beam limiter 45 is fixedly connected to the bottom end of the alignment ring 43; a snap fastener 42 is fixedly connected to the outer side of the alignment ring 43; when it is necessary to install or replace the beam limiter 45, the alignment ring 43 is aligned upward with the fixing ring 41, and then the alignment ring 43 is rotated. The rotation allows the snap fastener 42 on the alignment ring 43 to slide along the outer side of the curved strip 44 and form a snap. Through this rotation snap fastener method, the alignment ring 43 carrying the beam limiter 45 is detachably and quickly fixed to the fixing ring 41, thereby firmly installing the beam limiter 45 at the beam exit of the laser head 3.

[0024] Reference Figure 1The protective mechanism 5 includes an outer frame 51 and a frame door 56 for closing the opening of the outer frame 51; L-shaped plates 52 are fixedly connected to both ends of the outer frame 51, and the L-shaped plates 52 serve as the connecting bottom of the entire protective mechanism 5; a protrusion 53 is also fixedly connected to the front end of the L-shaped plate 52; in order to realize the automatic opening and closing of the frame door 56, the protective mechanism 5 is also provided with a hydraulic cylinder 54 as a power source and a connecting block 55 as a transmission component; the hydraulic cylinder 54 is rotatably mounted on the protrusion 53; the connecting block 55... One end of 5 is rotatably connected to the drive end of the hydraulic cylinder 54, while the other end is fixedly connected to the frame door 56. When the hydraulic cylinder 54 is activated, its drive end pulls or pushes the connecting block 55, thereby causing the frame door 56 to rotate around the axis, thus opening or closing the protective space. In order to enhance the stability and load-bearing capacity of the connection, the cross-section of the protrusion 53 is designed as T-shaped, and the cross-section of the connecting block 55 is also designed as T-shaped accordingly. This structural design ensures the reliability of the transmission path between the hydraulic cylinder 54 and the frame door 56.

[0025] In a preferred embodiment, to ensure smooth and stable opening and closing of the frame door 56 and prevent shaking or jamming during movement, an auxiliary component 57 is also provided between the frame door 56 and the outer frame 51; please refer to Figure 1 The auxiliary component 57 includes a fixed block 571, a connecting block 572, and a rotating rod 573. The fixed block 571 is fixedly connected to the outside of the frame door 56. The connecting block 572 is fixedly connected to the front end of the outer frame 51. The two ends of the rotating rod 573 are rotatably connected between the fixed block 571 and the connecting block 572, respectively. Through the coordinated movement of the four-bar or multi-bar linkage formed by the auxiliary component 57, the rotation trajectory of the frame door 56 is effectively constrained and supported, thereby ensuring the stability and reliability of the opening and closing action of the frame door 56.

[0026] The working principle is as follows: When processing is required, the hydraulic cylinder 54 in the protective mechanism 5 is driven to pull or push the frame door 56 through the connecting block 1 55, so that the frame door 56 rotates around the axis to open or close the processing space. During this process, the auxiliary component 57 set between the frame door 56 and the outer frame 51, through the coordinated linkage of its internal fixing block 571, connecting block 2 572 and rotating rod 573, ensures that the movement of the frame door 56 is smooth and stable, providing a stable internal environment for the processing.

[0027] Before processing or when changing processing tasks, the operator selects the corresponding beam limiting block 45 according to the required beam shape; then, the alignment ring 43 that fixes the beam limiting block 45 is aligned and attached to the fixing ring 41 fixed at the bottom of the laser head 3; then the alignment ring 43 is rotated so that the inclined buckle 42 on its outer side slides in and engages with the curved strip 44 on the outer side of the fixing ring 41, completing the quick locking; through this convenient rotary buckle installation, the shape of the laser beam can be quickly adjusted, solving the problem of complex or inefficient adjustment in traditional methods.

[0028] After the frame door 56 is closed to form a stable processing environment and the light limiting block 45 is installed in place, the linear motor 2 starts and precisely drives the processing table 1 fixed on it to move linearly according to the preset program; at the same time, the laser head 3 emits laser, and after the beam is shaped by the light limiting block 45, it acts on the chip on the processing table 1 with a predetermined shape of light spot to complete the mass processing task.
