Description

Technical Field

[0001] This utility model relates to the field of ring light sources, and specifically to a ring light source anti-collision mechanism. Background Technology

[0002] As an illumination component, a ring light source provides a clear contour image of the object being measured through a uniform light field distribution, making it a key component for ensuring measurement accuracy and inspection efficiency. In the fields of precision measurement and industrial inspection, ring light sources, along with other measuring instruments, are widely used for the inspection of dimensions, geometric tolerances, and surface defects in electronic components, mechanical parts, and optical components. With the development of industrial automation and intelligent manufacturing, the application of ring light sources in high-precision scenarios such as semiconductor inspection, precision assembly, and 3D scanning is becoming increasingly widespread, and the stability of their technical performance directly affects the reliability of the inspection results.

[0003] In existing flash detectors and measuring instruments, the ring light source typically adopts a modular design, consisting of a light source ring, a support frame, and an adjustment mechanism. The light source ring is usually a ring-shaped LED array or fluorescent tube, which is fixed to the lifting mechanism or rotating platform of the measuring equipment by a bracket; the adjustment mechanism is driven by a motor to adjust the illumination height of the light source.

[0004] However, existing ring light source designs have certain drawbacks. During equipment debugging, workpiece clamping, or robotic arm collaborative operations, operators or automated devices are prone to accidentally touching, colliding with, or scraping the light source ring, causing direct impact. For example, when the ring light source descends to the working position, if the workpiece stage height is improperly set, the bottom of the light source may collide hard with the object being measured. In multi-axis robotic arm movement path planning, failure to avoid the light source's activity area may also lead to scraping accidents. Such collisions will cause the light source ring to deform, detach, or break, affecting not only the consistency of measurement accuracy but also potentially increasing equipment downtime and maintenance costs. Therefore, there is an urgent need to design a ring light source anti-collision mechanism with protective capabilities, achieving collision mitigation and protection through structural optimization, thereby improving equipment reliability and service life. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide a ring light source anti-collision mechanism to solve the technical problem of how to improve the anti-collision or anti-scratching protection of the ring light source in the background art, so as to ensure the stability and reliability of the ring light source during lifting and lowering.

[0006] The objective of this utility model is achieved through the following means:

[0007] An anti-collision mechanism for a ring light source includes a movable module and a movable bracket. The movable module is connected to one end of the movable bracket via a sliding seat. The movable module can drive the movable bracket to reciprocate. An LED ring light source is provided at the other end of the movable bracket. An annular bracket for mounting the LED ring light source is provided at the end of the movable bracket. The LED ring light source and the annular bracket are paired and installed. A protective frame for protecting the LED ring light source is detachably held on the annular bracket. The protective frame and the LED ring light source are sleeved together. A protective plate is snapped to the end of the protective frame near the LED ring light source. A silicone protective pad is adhered to the inner side of the protective plate. A limit plate is snapped to the end of the protective frame near the annular bracket. Multiple elastic elements are provided between the limit plate and the annular bracket. The elastic elements can provide a continuous elastic force to the limit plate, causing the protective frame to move the protective plate away from the LED ring light source.

[0008] Furthermore, as described above, one end of the movable module is connected to a drive motor, which drives the sliding seat to reciprocate along the movable module. The sliding seat is connected to one end of the movable bracket via a connecting plate.

[0009] The mobile module is connected to the mobile support via a sliding base and is driven by a drive motor to move back and forth, enabling precise displacement control of the ring light source.

[0010] Furthermore, as described above, the outer side of the annular bracket is provided with a guide groove, and the inner wall of the protective frame is provided with a guide block that engages with the guide groove. The protective frame can be adjusted along the extension direction of the guide groove via the guide block.

[0011] The outer side of the ring bracket has a guide groove that engages with the guide block on the inner wall of the protective frame, allowing the protective frame to move and adjust along the extension direction of the guide groove. In the event of a collision, the sliding guide action of the guide block and the guide groove guides the protective frame to move along a preset path, preventing direct collision with the LED ring light source.

[0012] Furthermore, as described above, the protective frame has a positioning buckle at its end, and the protective plate has a positioning slot that is inserted and connected to the positioning buckle, so that the protective plate is inserted and connected to the positioning buckle through the positioning slot. The protective plate has a through hole in the middle to avoid the LED ring light source irradiation end, and a silicone protective pad is bonded to the inner side of the protective plate, so that the silicone protective pad is placed between the LED ring light source and the protective plate.

[0013] When the protective plate is squeezed by external force, the silicone protective pad comes into contact with the LED ring light source and can absorb the impact energy and disperse the stress, preventing the LED ring light source from deforming or breaking due to direct impact. At the same time, the through-hole design ensures that the light source illumination function is not affected, achieving a balance between protection and function.

[0014] Furthermore, as described above, the limiting plate has protruding mounting buckles, and the protective frame has mounting slots that engage with the mounting buckles, so that the limiting plate and the protective frame are connected by a snap-fit ​​mechanism. The limiting plate also has an opening for avoiding the movement of the support bracket.

[0015] Under the action of the spring force, the limiting plate continues to approach the ring bracket, causing the protective frame to move the protective plate away from the LED ring light source to form an anti-collision buffer gap. When there is a collision, the protective frame overcomes the spring force and moves towards the light source. The impact is buffered by the anti-collision buffer gap and the elastic force of the elastic element. When resetting, the spring force drives the protective frame back to its original position, restoring the anti-collision buffer gap.

[0016] Furthermore, as described above, a protruding guide post is formed on the inner side of the limiting plate, and the elastic element is composed of a spring. One end of the spring is sleeved with the guide post and fixedly connected to the inner side of the limiting plate. An installation hole is provided on the annular bracket, and the other end of the spring is inserted into the installation hole for fixed connection. This allows the spring to drive the limiting plate to move closer to the annular bracket through its reset force, and to move the protective plate away from the LED annular light source. An anti-collision buffer gap is formed between the protective plate and the LED annular light source.

[0017] The design of the spring being fixedly connected to the inner side of the limiting plate through the guide post and inserted into the mounting hole of the annular bracket ensures that the elastic force direction of the elastic element is consistent with the movement direction of the protective frame. At the same time, the continuous elastic force of the spring can maintain a stable gap between the protective plate and the LED ring light source, preventing protective failure or excessive compression caused by gap changes.

[0018] Furthermore, as described above, when the protective plate is subjected to collision and compression, the protective frame overcomes the spring force and moves closer to the LED ring light source, providing a buffering effect through the anti-collision buffer gap. When the collision and compression on the protective plate are eliminated, the spring force resets and drives the protective frame to move the protective plate back to its original position, thus creating a buffer between the protective plate and the LED ring light source.

[0019] When the protective plate is impacted and squeezed, the protective frame moves along the guide groove through the guide block to compress the spring. It uses the anti-collision buffer gap to absorb the impact energy. After the compression is eliminated, the spring force drives the protective frame to reset and re-form the buffer gap. This realizes a dynamic protection cycle of collision-buffering-reset, which effectively reduces the risk of damage to the light source caused by hard collisions and extends the service life of the equipment.

[0020] Furthermore, as described above, a proximity sensor is connected to the movable bracket. When the limiting plate moves close to the proximity sensor, the proximity sensor can trigger an alarm.

[0021] The mobile support is connected to a proximity sensor. When the limit plate reaches the limit due to collision and compression, the sensor will trigger an alarm when the mobile support moves close to it. This can monitor the displacement status of the protective frame in real time, provide early warning in the early stages of a collision, and prevent damage to the LED ring light source due to excessive compression of the anti-collision buffer gap. At the same time, it provides fault location information for equipment maintenance, improving equipment reliability and maintenance efficiency.

[0022] The beneficial effects of this utility model are as follows: The protective frame and the LED ring light source are sleeved together to form a surrounding physical barrier. The end of the protective frame near the ring support is connected to the ring support through multiple elastic elements set between the limiting plate and the ring support. The elastic elements can provide a continuous elastic force to the limiting plate to approach the ring support. When the protective frame is impacted by an external force, the protective frame drives the protective plate to move towards the LED ring light source, and absorbs the impact energy through the elastic deformation of the elastic elements. After the external force disappears, the elastic elements reset, allowing the protective frame to return to its original position. The silicone protective pad bonded to the inner side of the protective plate can prevent the LED ring light source from deforming, falling off, or breaking due to hard collisions. Through the synergistic effect of the protective frame, silicone protective pad, elastic elements, and limiting plate, a protective mechanism is formed for the LED ring light source during equipment debugging, workpiece clamping, or robotic arm collaborative operation, effectively mitigating various collision impacts, improving the stability and reliability of the LED ring light source during lifting and lowering, reducing equipment downtime risk and maintenance costs, and extending equipment service life.

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer, the following describes the solution in further detail with reference to the accompanying drawings and embodiments.

[0032] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this scheme and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0033] In this embodiment, refer to Figures 1-6 The specific implementation of the ring light source anti-collision mechanism includes a movable module 1 and a movable bracket 2. The movable module 1 is connected to one end of the movable bracket 2 via a sliding seat 3. The movable module 1 can drive the movable bracket 2 to reciprocate. An LED ring light source 4 is provided at the other end of the movable bracket 2. An annular bracket 5 for mounting the LED ring light source 4 is provided at the end of the movable bracket 2. The LED ring light source 4 and the annular bracket 5 are paired and installed. A protective frame 6 for protecting the LED ring light source 4 is detachably held on the annular bracket 5. The protective frame 6 and the LED ring light source 4 are sleeved together. A protective plate 7 is snapped to the end of the protective frame 6 near the LED ring light source 4. A silicone protective pad 24 is adhered to the inner side of the protective plate 7. A limit plate 8 is snapped to the end of the protective frame 6 near the annular bracket 5. Multiple elastic elements 9 are provided between the limit plate 8 and the annular bracket 5. The elastic elements 9 can provide a continuous elastic force to the limit plate 8 to move closer to the annular bracket 5, so that the protective frame 6 moves the protective plate 7 away from the LED ring light source 4.

[0034] Specifically, in this embodiment, the protective plate 7 is disposed at the bottom of the LED ring light source 4. By bonding a silicone protective pad 24 to the inner side of the protective plate 7, and forming an anti-collision buffer gap 22 between the inner side of the protective plate 7 and the LED ring light source 4, the direct contact between the operator or the automated device and the LED ring light source 4 is effectively prevented, thus avoiding direct impact damage caused by accidental contact, collision or scratch.

[0035] Specifically, in this embodiment, the protective frame 6 and the ring bracket 5 are connected by a detachable snap-fit, which facilitates quick disassembly, replacement or maintenance of the protective components and improves equipment maintenance efficiency; at the same time, the end of the protective frame 6 near the LED ring light source 4 is connected to the protective plate 7 by a snap-fit, ensuring that the protective plate 7 is installed firmly and that the silicone protective pad 24 is easy to replace.

[0036] One end of the mobile module 1 is connected to a drive motor 10, which drives the sliding seat 3 to reciprocate along the mobile module 1. The sliding seat 3 is connected to one end of the mobile bracket 2 through a connecting plate 11.

[0037] The mobile module 1 is connected to the mobile support 2 via the sliding base 3 and is driven to reciprocate by the drive motor 10, which can realize precise displacement control of the ring light source.

[0038] Specifically, in this embodiment, the moving module 1 is composed of a lead screw module, with one end of the lead screw connected to the output end of the drive motor 10, and the lead screw connected to the sliding seat 3 through a nut, so that the rotation of the lead screw can drive the sliding seat 3 to move along the lead screw axis.

[0039] The outer side of the annular bracket 5 is provided with a guide groove 12, and the inner wall of the protective frame 6 is provided with a guide block 13 that is engaged with the guide groove 12. The protective frame 6 can be adjusted along the extension direction of the guide groove 12 by means of the guide block 13.

[0040] The outer side of the ring bracket 5 has a guide groove 12 that engages with the guide block 13 on the inner wall of the protective frame 6, allowing the protective frame 6 to move and adjust along the extension direction of the guide groove 12. When a collision occurs, the guide block 13 and the guide groove 12 slide and guide the protective frame 6 to move along a preset path, preventing direct collision with the LED ring light source 4.

[0041] Specifically, the protective frame 6 is composed of a protective ring, which is fitted onto the outside of the ring bracket 5 and provides protection for the LED ring light source 4.

[0042] The protective frame 6 has a positioning buckle 14 at its end, and the protective plate 7 has a positioning slot 15 that is inserted and connected to the positioning buckle 14, so that the protective plate 7 is inserted and connected to the positioning buckle 14 through the positioning slot 15. The protective plate 7 has a through hole 16 in the middle to avoid the irradiation end of the LED ring light source 4. The silicone protective pad 24 is bonded to the inner side of the protective plate 7, so that the silicone protective pad 24 is placed between the LED ring light source 4 and the protective plate 7.

[0043] When the protective plate 7 is squeezed by external force, the silicone protective pad 24 comes into contact with the LED ring light source 4 and can absorb the impact energy and disperse the stress, preventing the LED ring light source 4 from deforming or breaking due to direct impact. At the same time, the through hole 16 design ensures that the light source illumination function is not affected, thus achieving a balance between protection and function.

[0044] The limiting plate 8 has a protruding mounting buckle 17, and the protective frame 6 has a mounting slot 18 that is matched with the mounting buckle 17, so that the limiting plate 8 and the protective frame 6 are connected by a buckle. The limiting plate 8 has an opening 19 for avoiding the moving bracket 2.

[0045] Under the action of the spring force, the limiting plate 8 continues to approach the ring bracket 5, causing the protective frame 6 to move the protective plate 7 away from the LED ring light source 4 to form an anti-collision buffer gap 22. When there is a collision, the protective frame 6 overcomes the spring force and moves towards the light source. The impact is buffered by the anti-collision buffer gap 22 and the elastic force of the elastic element 9. When resetting, the spring force drives the protective frame 6 to return to its original position and restore the anti-collision buffer gap 22.

[0046] The inner side of the limiting plate 8 has a protruding guide post 20. The elastic element 9 is made of a spring. One end of the spring is sleeved with the guide post 20 and fixedly connected to the inner side of the limiting plate 8. The annular bracket 5 has an installation hole 21. The other end of the spring passes through the installation hole 21 for fixed connection. The spring can drive the limiting plate 8 to move closer to the annular bracket 5 through the reset elastic force, and move the protective plate 7 away from the LED annular light source 4. An anti-collision buffer gap 22 is formed between the protective plate 7 and the LED annular light source 4.

[0047] The spring is fixedly connected to the inner side of the limiting plate 8 through the guide post 20 and inserted into the mounting hole 21 of the ring bracket 5. This design ensures that the elastic force direction of the elastic element 9 is consistent with the movement direction of the protective frame 6. At the same time, the continuous elastic force of the spring can maintain a stable gap between the protective plate 7 and the LED ring light source 4, preventing protection failure or excessive compression caused by gap changes.

[0048] When the protective plate 7 is subjected to collision and compression, the protective frame 6 overcomes the elastic force of the spring and moves closer to the LED ring light source 4, and performs a buffering effect through the anti-collision buffer gap 22. When the collision and compression on the protective plate 7 is eliminated, the elastic force of the spring can drive the protective frame 6 to move the protective plate 7 to reset, so that a buffer is formed between the protective plate 7 and the LED ring light source 4.

[0049] When the protective plate 7 is subjected to impact and compression, the protective frame 6 moves along the guide groove 12 via the guide block 13 to compress the spring. The impact energy is absorbed by the anti-collision buffer gap 22. After the compression is eliminated, the spring force drives the protective frame 6 to reset and re-form the buffer gap. This achieves a dynamic protection cycle of collision-buffering-reset, effectively reducing the risk of damage to the light source caused by hard impact and extending the service life of the equipment.

[0050] The movable support 2 is connected to a proximity sensor 23. When the limiting plate 8 moves close to the proximity sensor 23, the proximity sensor 23 can trigger an alarm.

[0051] The mobile support 2 is connected to the proximity sensor 23. When the limit plate 8 reaches the limit due to collision and compression, the sensor will trigger an alarm when the plate moves close to the sensor. The sensor can monitor the displacement status of the protective frame 6 in real time and provide early warning in the early stage of the collision. This will prevent the anti-collision buffer gap 22 from being over-compressed and causing damage to the LED ring light source 4. At the same time, it will provide fault location information for equipment maintenance and improve equipment reliability and maintenance efficiency.

[0052] The specific operating principle in this embodiment is as follows:

[0053] The protective frame 6 is clamped and installed with the ring bracket 5. The limiting plate 8 is connected to the spring and is clamped and connected with the mounting slot 18 of the protective frame 6 through the mounting buckle 17. The spring is placed between the limiting plate 8 and the ring bracket 5. The spring can drive the limiting plate 8 to continuously move closer to the ring bracket 5. The inner side of the protective plate 7 is glued with silicone protective pad 24. The protective plate 7 is clamped and connected with the positioning buckle 14 of the protective frame 6 through the positioning slot 15. The silicone protective pad 24 is placed between the protective plate 7 and the LED ring light source 4.

[0054] The protective frame 6 and the LED ring light source 4 are fitted together to form a surrounding physical barrier. The protective plate 7 and the limiting plate 8 are distributed at both ends of the protective frame 6 to prevent the protective frame 6 from falling directly. When the moving module 1 descends and the protective frame 6 is subjected to an accidental collision, the protective frame 6 drives the protective plate 7 to move towards the LED ring light source 4. The anti-collision buffer gap 22 provides a certain buffer distance for the LED ring light source 4 to prevent direct collision with the LED ring light source 4. At the same time, the soft effect of the silicone protective pad 24 further prevents collision and scratching of the LED ring light source 4. The elastic deformation of the elastic element 9 absorbs the impact energy. After the external force disappears, the elastic element 9 resets and the protective frame 6 returns to its original position.

[0055] Through the synergistic effect of the protective frame 6, silicone protective pad 24, elastic element 9 and limiting plate 8, a protective mechanism is formed for the LED ring light source 4 during equipment debugging, workpiece clamping or robotic arm collaborative operation. This effectively reduces various collision impacts, improves the stability and reliability of the LED ring light source 4 during lifting and lowering, reduces equipment downtime risk and maintenance costs, and extends equipment service life.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
