Description

Technical Field

[0001] This invention relates to the field of microscope illumination technology, specifically to a microscope illumination control device, a microscope module, and a microscope. Background Technology In the field of precision electronics repair, microscopes are crucial tools for chip-level repair (such as BGA packaged component rework and PCB circuit testing). The lighting control system directly impacts observation results. Traditional microscopes often use a uniform illumination method, where all LEDs are lit simultaneously. This can lead to glare and shadows when observing complex structures, reducing visibility. To improve lighting performance, zoned lighting control schemes have emerged, allowing users to select specific lighting areas to avoid these problems.

[0002] However, existing zoned lighting typically uses separate control interfaces, such as selecting lighting zones via independent buttons or toggle switches, and adjusting brightness via separate knobs or potentiometers. This design results in a large number of physical buttons and a complex user interface, requiring users to frequently switch operating methods, thus impacting repair efficiency. Furthermore, in electronic repair scenarios, technicians often need to operate microscopes with one hand while performing repairs; too many buttons increase the difficulty of operation and the risk of accidental touches.

[0003] Therefore, simplifying the lighting control operations for maintenance personnel has become an urgent technical problem to be solved. Summary of the Invention

[0004] Based on the above situation, the main objective of this invention is to provide a microscope lighting control device, a microscope module, and a microscope to simplify lighting control for maintenance personnel.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, embodiments of the present invention disclose a microscope illumination control device for illuminating the area to be observed under a microscope, comprising: The ring-shaped body is used to cover the microscope cylinder or tube. The illumination module, which includes multiple partitioned LEDs, is located at the bottom of the annular body. After the annular body is fitted onto the microscope cylinder or tube, the light-emitting surface of the illumination module faces the area to be observed by the microscope. The pulsator button is scrolled on the ring-shaped body and supports axial pressing operation and radial oscillation operation. The control unit is electrically connected to the pulsator button and the lighting module respectively; the control unit triggers the lighting module to illuminate in zones in response to the first operation of the pulsator button, and adjusts the brightness of the lighting lamps in the lighting module in response to the second operation of the pulsator button; wherein the first operation and the second operation are respectively an axial pressing operation and a radial oscillating operation.

[0006] Optionally, the sidewall of the annular body extends into an extension portion, the pulsator button is located on the side of the extension portion, and the control unit is located inside the extension portion.

[0007] Optionally, it also includes: The USB Type-C interface is located on the side of the extension, different from the pulsator button. The USB Type-C interface is used to provide operating power to the control unit and lighting module, and / or to provide a program update and burning interface for the control unit.

[0008] Alternatively, the extension is integrally formed from the annular body, or... The extension and the annular body are separate structures. The annular body is a ring-shaped structure with an outwardly protruding edge, and the extension is engaged with the protruding edge.

[0009] Optionally, the sidewalls of the annular body are provided with several fasteners for securing the annular body to the microscope column or tube.

[0010] Optionally, the lighting module includes multiple LED beads distributed in an array and divided into multiple independently controllable lighting zones.

[0011] Optionally, the first operation is an axial pressing operation, and the second operation is a radial undulating operation.

[0012] Optionally, the control unit responds to axial pressing operations by cyclically switching preset lighting zone modes.

[0013] Secondly, embodiments of the present invention disclose a microscope module, comprising: An imaging lens is used to magnify and image the area to be observed. The microscope illumination control device disclosed in the first aspect above has an annular body that covers the tube of the imaging lens.

[0014] Thirdly, embodiments of the present invention disclose a microscope, including: the microscope illumination control device disclosed in the first aspect above. Beneficial effects

[0015] According to embodiments of the present invention, a microscope illumination control device, microscope module, and microscope are disclosed. The ring-shaped body design makes the entire device easy to use and versatile. Through its coverable ring structure, it can be mounted on most microscopes without complex modifications to the microscope itself. When the ring-shaped body is securely mounted on the microscope, the illumination module at its bottom is suspended above the area to be observed. The zoned setting and control of the illumination module specifically solves the inherent problems of reflection and shadow interference in traditional uniform illumination methods. A single rotary button integrates both axial pressing and radial oscillation operations, corresponding to triggering zoned illumination and adjusting brightness functions, respectively. On the one hand, this simplifies the operations required for each adjustment; maintenance personnel do not need to switch between multiple buttons or knobs, and can complete all illumination adjustments with a single thumb. On the other hand, precise and rapid illumination control allows maintenance personnel to quickly obtain the best observation field without shadows or glare, making it easier to identify minor solder joint defects or circuit problems, thus improving the success rate and quality consistency of maintenance work.

[0016] Furthermore, by integrating the pulsator button, lighting module, control unit, etc., onto the ring-shaped body, a highly compact integrated structure is formed, making the overall device robust, compact, and without taking up extra space. Other beneficial effects of the present invention will be explained in detail through the introduction of specific technical features and technical solutions in specific embodiments. Those skilled in the art should be able to understand the beneficial technical effects brought about by these technical features and technical solutions through the introduction of these technical features and technical solutions.

[0017] The embodiments of the present invention will now be described with reference to the accompanying drawings. In the drawings: Figure 1 This is a schematic diagram of the first-view structure of a microscope illumination control device disclosed in this embodiment; Figure 2 This is a schematic diagram of the second-view structure of a microscope illumination control device disclosed in this embodiment; Figure 3 This is a schematic diagram of an example microscope structure. Detailed Implementation

[0018] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail, but well-known methods, processes, procedures, and elements are not described in detail in order to avoid obscuring the essence of the present invention.

[0019] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0020] Unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."

[0021] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0022] To simplify lighting control for maintenance personnel, this embodiment discloses a microscope lighting control device. Please refer to [reference needed]. Figure 1 and Figure 2 , Figure 1 This is a first-view structural diagram of a microscope illumination control device disclosed in this embodiment. Figure 2 This is a second-view structural diagram of a microscope illumination control device disclosed in this embodiment. The microscope illumination control device disclosed in this embodiment is used to illuminate the area to be observed under the microscope. Specifically, please refer to... Figure 3 , Figure 3 This is a schematic diagram of an example microscope structure, showing the microscope tube 100 and the area to be observed below it (such as a chip on a PCB board). In precision electronics repair, because the components to be observed (such as chip pins and solder joints) have a three-dimensional structure, uniform omnidirectional illumination often produces heavy shadows on the back or sides of the components, or creates strong reflections on smooth surfaces, obscuring critical details. To obtain the best observation results, it is necessary to illuminate from a specific angle to eliminate shadows and control reflections, which requires precise control of the illuminated area. The illumination control device of this invention is designed to meet this need.

[0023] Please refer to Figure 1 and Figure 2 The microscope illumination control device disclosed in this embodiment includes: a ring-shaped body 1, an illumination module 2, a rotary knob 3, and a control unit, wherein: The annular body 1 is used to cover the microscope cylinder or tube. The annular body 1 is preferably made of a lightweight material with sufficient structural strength (such as engineering plastics or metal), and its inner diameter is adapted to the outer diameter of the microscope cylinder or tube. It can be quickly installed and fixed through interference fit or by setting a simple fastening mechanism (such as elastic clamps, snap-fits, etc.). The design of the annular body 1 allows the entire illumination control device to be easily added to various models of microscopes as a standalone module without structural modifications to the microscope body, thus offering high versatility. Of course, in practical implementation, the annular body 1 can also be designed as an integral part of the microscope to increase its secureness.

[0024] Please refer to Figure 2 The illumination module 2 is located at the bottom of the annular body 1. The illumination module 2 includes multiple partitioned LED beads (preferably LED beads) arranged in a ring or array and divided into multiple independently controllable illumination zones. When the annular body 1 is fitted onto the microscope cylinder or tube 100, the emitting surface of the illumination module 2 faces the area to be observed below the microscope. By independently controlling the illumination of the LED beads in different zones, the object to be observed can be illuminated from different angles. For example, when observing the pins on the side of a chip, the lateral LED beads can be illuminated individually, thus avoiding shadows cast on the back of the pins by the light on the top of the pins, making the pin outline clearly visible.

[0025] Please refer to Figure 1 and Figure 2 The pulsator button 3 is rotatably mounted on the annular body 1. In this embodiment, the pulsator button 3 supports axial pressing and radial undulating operations. Specifically, the pulsator button 3 supports pressing along its axis (Z-axis direction) and radial undulating around its axis (X-axis direction). In a preferred embodiment, the pulsator button 3 preferably adopts a knob with an encoder function, capable of recognizing pressing events and rotation direction / steps. Of course, in other embodiments, pressing events and rotation direction / steps can also be recognized by setting contacts on the pulsator button 3. In this embodiment, the position of the pulsator button 3 should be convenient for a user (e.g., a maintenance personnel) to reach and operate with one thumb when operating the microscope.

[0026] The control unit (not shown in the figure, but may be located inside the annular body 1) is electrically connected to the pulsator button 3 and the lighting module 2, respectively. The control unit triggers zone lighting in the lighting module 2 in response to a first operation of the pulsator button 3, and adjusts the brightness of the lighting bulbs in the lighting module 2 in response to a second operation of the pulsator button 3; wherein the first and second operations are respectively an axial pressing operation and a radial oscillation operation. Specifically, the control unit may contain a microprocessor and related drive circuitry, or it may contain control logic circuitry and drive circuitry.

[0027] In this embodiment, the control unit is configured to respond to different operations of the pulsator button 3: when a first operation (e.g., axial pressing) is detected, the control unit triggers the lighting module 2 to switch the zone lighting mode, such as cyclically switching between full-area lighting, left-side lighting, right-side lighting, and front-side lighting in a preset order; when a second operation (e.g., radial oscillation) is detected, the control unit adjusts the brightness of the currently lit LED, for example, oscillating to the left to decrease the brightness and oscillating to the right to increase the brightness. Brightness adjustment can be achieved through PWM.

[0028] Of course, in practice, the radial oscillation control unit can trigger the lighting module 2 to switch between zone lighting modes, and the brightness of the currently lit LED can be adjusted by axial pressing. For example, oscillating to the left (or right) cycles through full-area lighting, left-side lighting, right-side lighting, and front-side lighting in a preset sequence; or, when pressing axially, the brightness gradually increases or decreases, with a long press event determining whether to increase or decrease the brightness. Specifically, the control logic can be configured according to user habits.

[0029] In a preferred embodiment, the first operation is an axial pressing operation, and the second operation is a radial undulating operation. Specifically, the control unit responds to the axial pressing operation by cyclically switching between preset lighting zone modes. This allows the user to quickly switch lighting zones and compare visual effects.

[0030] To make the overall structure of the lighting control device more compact, in an optional embodiment, the side wall of the annular body 1 extends into an extension portion 11, the pulsator button 3 is disposed on the side of the extension portion 11, and the control unit is disposed within the extension portion 11. Specifically: Please refer to Figure 1 and Figure 2 In this embodiment, an extension 11 extends from the sidewall of the annular body 1. This extension 11 protrudes outward from the sidewall of the annular body 1, and its shape and size are designed to accommodate the control unit and mount the pulsator button 3. In specific implementation: The rotary dial button 3 is located on the side of the extension 11. Specifically, a mounting hole is provided on the side wall of the extension 11, and the rotary dial button 3 is rolled within this mounting hole by means of a bearing or sliding fit, so that part of the surface of the rotary dial button 3 is exposed to the outside of the extension 11 for easy user operation. The axial direction of the rotary dial button 3 is approximately perpendicular to the side wall of the extension 11, thereby allowing for smooth axial pressing and radial oscillation operations. This arrangement places the rotary dial button 3 in an area easily accessible to the user's thumb when holding the microscope, thus facilitating user operation.

[0031] The control unit is housed within the extension 11. An internal cavity is formed within the extension 11 to accommodate the main components of the control unit, such as a printed circuit board (PCB), microprocessor, driver chip, and passive components. The control unit can be connected to the LEDs of the lighting module 2 via flexible circuitry or wires.

[0032] With the design of the extension 11, the pulsator button 3 and the control unit are compactly integrated on the side of the ring body 1, making the overall structure of the lighting control device more compact and not taking up extra space.

[0033] In an optional embodiment, the microscope illumination control device further includes a USB Type-C interface disposed on the side of the extension 11, different from the pulsator button 3. The USB Type-C interface is used to provide operating power to the control unit and the illumination module 2, and / or to provide a program update and burning interface for the control unit.

[0034] In this embodiment, the USB Type-C interface is located on the side of the extension 11, and on a different side from the pulsator button 3, in order to avoid operational interference.

[0035] In one embodiment, the USB Type-C interface can be used to connect an external power adapter or power bank to provide a stable operating voltage for the control unit and lighting module 2, ensuring that the lighting system continues to operate during long-term maintenance operations.

[0036] In another embodiment, when the control unit includes a programmable processor, the USB Type-C interface is reused as a programming interface, allowing users to connect a programmer via a standard data cable and quickly update firmware to optimize partitioned lighting logic or brightness adjustment algorithms. In this embodiment, through hardware circuit design, a complete programming data path can be automatically established only when the dedicated programmer is inserted into the USB Type-C interface in a specific orientation, thereby achieving programming without disassembly, as detailed below: During the printed circuit board design phase, some physical pins of the USB Type-C interface are selected and connected to the corresponding programming function pins of the processor (such as the serial data input / output interface SWDIO, the serial clock interface SWCLK, and the reset signal nRST) via PCB traces. When a dedicated programmer is inserted into the USB Type-C interface in a specific orientation, these pins are remapped to standard programming signal pins, thus entering programming mode and enabling processor programming updates without disassembling the device. When the device is not connected to a programmer or is connected to standard accessories such as chargers or data cables, due to physical connection mismatch, these selected physical pins of the USB Type-C interface cannot form an effective path for programming with the external device, and the data exchange path is not connected. All pins in the USB Type-C interface maintain their standard protocol functions (such as charging and USB data transfer).

[0037] As can be seen, this embodiment utilizes the existing interfaces of the equipment, eliminating the need for opening dedicated debugging ports or disassembling the outer casing (no disassembly required), thereby improving the efficiency of production debugging and on-site maintenance.

[0038] To achieve a reliable connection between the extension 11 and the annular body 1 and to adapt to different production and assembly requirements, in specific embodiments, the extension 11 can be integrally formed with the annular body 1 or it can be a separate structure, as detailed below: In one embodiment, the extension 11 is integrally formed from the annular body 1. In this embodiment, the annular body 1 and the extension 11 of its sidewalls are manufactured as a complete single component. During the mold design stage, the cavity of the annular body 1 and the extension 11 is designed as a whole. This improves the structural strength and stability.

[0039] In another embodiment, the extension 11 and the annular body 1 are separate structures. The annular body 1 is a ring-shaped structure with an outwardly extending flange, and the extension 11 is engaged with the flange. In this embodiment, The annular body 1 is designed as a ring-shaped structure with an outwardly extending flange, which typically extends horizontally or at a slight angle from the side wall of the annular body 1. Correspondingly, the extension 11 is designed with a slot or hook that matches the shape of the flange. During assembly, simply aligning the snap-fit ​​structure of the extension 11 with the flange of the annular body 1 achieves snap-fit ​​fixation. The split structure of this embodiment allows the annular body and the extension to be manufactured using their respective suitable materials or processes, improving production flexibility. Furthermore, it facilitates the replacement and maintenance of parts.

[0040] To achieve a reliable connection between the annular body 1 and the microscope cylinder or tube, in an optional embodiment, please refer to... Figure 1 and Figure 2 The annular body 1 has several fasteners 12 extending through its sidewalls, used to secure the annular body 1 to the microscope column or barrel. Specifically, the fasteners 12 can be screws or bolts, or other types of fasteners such as elastic clamps or quick-release mechanisms that can secure the annular body 1, to adapt to different installation scenarios.

[0041] This embodiment also discloses a microscope module, including: an imaging lens and a microscope illumination control device disclosed in the above embodiment, wherein: Imaging lenses are used to magnify and image the area to be observed. The annular body of the microscope illumination control device covers the tube of the imaging lens.

[0042] This embodiment also discloses a microscope, including the microscope illumination control device disclosed in the above embodiment.

[0043] According to embodiments of the present invention, a microscope illumination control device, microscope module, and microscope are disclosed. The ring-shaped body design makes the entire device easy to use and versatile. Through its coverable ring structure, it can be mounted on most microscopes without complex modifications to the microscope itself. When the ring-shaped body is securely mounted on the microscope, the illumination module at its bottom is suspended above the area to be observed. The zoned setting and control of the illumination module specifically solves the inherent problems of reflection and shadow interference in traditional uniform illumination methods. A single rotary button integrates both axial pressing and radial oscillation operations, corresponding to triggering zoned illumination and adjusting brightness functions, respectively. On the one hand, this simplifies the operations required for each adjustment; maintenance personnel do not need to switch between multiple buttons or knobs, and can complete all illumination adjustments with a single thumb. On the other hand, precise and rapid illumination control allows maintenance personnel to quickly obtain the best observation field without shadows or glare, making it easier to identify minor solder joint defects or circuit problems, thus improving the success rate and quality consistency of maintenance work.

[0044] Furthermore, by integrating the pulsator button, lighting module, control unit, etc., onto the ring-shaped body, a highly compact integrated structure is formed, making the overall device robust, compact, and without taking up extra space.

[0045] Those skilled in the art will understand that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0046] It should be understood that the above embodiments are merely exemplary and not restrictive. Various obvious or equivalent modifications or substitutions that can be made by those skilled in the art regarding the above details without departing from the basic principles of the present invention will be included within the scope of the claims of the present invention.
