[0002] In pathological testing, tissue samples undergo fixation, dehydration, clearing, paraffin impregnation, and embedding to ultimately form a paraffin block for section analysis. Medical injection molded parts, serving as containers for these samples, are often lined with mesh to prevent sample displacement during use.

[0019] The embodiments of this utility model application will be described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model application, but should not be used to limit the scope of this utility model application. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model application.

[0020] Combination Figures 1-4 As shown, a visual inspection supplementary lighting device includes a base 1, a movable frame 2 on the base 1, and a video acquisition mechanism 3 on the movable frame 2. The video acquisition mechanism 3 includes a first mounting frame 31 and a second mounting frame 32 on the movable frame 2. A camera 311 is mounted on the first mounting frame 31, and a supplementary light 321 is mounted on the second mounting frame 32. When the robotic arm picks up the medical injection molded part 8 and places it above the supplementary light 321, the camera 311 takes a picture of it and sends the acquired image to the inspection terminal. The inspection terminal compares the acquired image with a specified image and determines whether it is qualified.

[0021] This invention proposes a visual inspection supplementary lighting device. The base 1 provides a stable mounting platform for other components, ensuring the device can be stably placed in its respective working environment. A movable frame 2 is mounted on the base 1, connecting the base 1 and the video acquisition mechanism 3, and may have some mobility to adjust the position and orientation of the video acquisition mechanism 3. The video acquisition mechanism 3 consists of a first mounting frame 31 and a second mounting frame 32, both mounted on the movable frame 2.

[0022] A camera 311 is mounted on the first mounting bracket 31. The camera 311 is a key component for acquiring image information, and its function is to capture images of the target object. A supplementary light 321 is mounted on the second mounting bracket 32. The supplementary light 321 provides sufficient light for the camera 311 to capture images of the target object, ensuring that the captured images are clear and accurate, and reducing image quality problems caused by insufficient or uneven lighting.

[0023] Place the visual inspection supplementary lighting device in a suitable working position, ensuring the base 1 is stable and the movable frame 2 is adjusted to the appropriate position and angle to enable the video acquisition mechanism 3 to function normally. Simultaneously, ensure the supplementary light 321 is emitting light normally, the camera 311 is acquiring images normally, and a communication connection is established with the inspection terminal. The robotic arm grasps the medical injection molded part 8 above the supplementary light 321. At this point, the medical injection molded part 8 is within the shooting range of the camera 311, and the supplementary light 321 provides sufficient light for the camera 311 to capture images of the medical injection molded part 8. The camera 311 captures image information of the medical injection molded part 8 located above the supplementary light 321.

[0024] Camera 311 sends the captured images to the inspection terminal. Upon receiving the images, the inspection terminal compares them with pre-defined standard images. Using specific image processing algorithms and judgment rules, the inspection terminal determines whether the captured images meet the specified requirements, and thus determines whether the medical injection molded part 8 is qualified. If the captured image matches the specified image in all features, the medical injection molded part 8 is deemed qualified; otherwise, it is deemed unqualified.

[0025] This visual inspection supplementary lighting device, through a reasonable structural design, utilizes the cooperation of camera 311 and supplementary light 321 to acquire images of target objects, and completes the quality judgment of target objects through interaction with the inspection terminal.

[0026] Combination Figure 2 , Figure 3 and Figure 4 As shown, the movable frame 2 includes a fixed seat 21 slidably connected to the base 1. The fixed seat 21 is provided with an adjustment mechanism 4 for adjusting the height of the video acquisition mechanism 3. Guide screws 5 are provided on both sides of the adjustment mechanism 4. The guide screws 5 pass through the first mounting frame 31 and the second mounting frame 32 in sequence perpendicular to the fixed seat 21.

[0027] Specifically, the fixed base 21 is slidably connected to the base 1, allowing the fixed base 21 to move within a certain range on the base 1, thereby adjusting the position of the movable frame 2 on the base 1 to adapt to different work scenarios and needs.

[0028] The adjustment mechanism 4 is mounted on the fixed base 21 and is a key component used to adjust the height of the video acquisition mechanism 3. Through the adjustment mechanism 4, the height position of the video acquisition mechanism 3 relative to the fixed base 21 can be changed, thereby adjusting the height of video acquisition components such as the camera 311 and the supplementary light 321. Guide screws 5 are located on both sides of the adjustment mechanism 4 and pass perpendicularly to the fixed base 21 through the first mounting bracket 31 and the second mounting bracket 32. The guide screws 5 guide and support the first mounting bracket 31 and the second mounting bracket 32, ensuring that they maintain a stable movement trajectory during height adjustment, avoiding swaying or deviation, and guaranteeing the stability and accuracy of the video acquisition mechanism 3. Simultaneously, the guide screws 5 may also cooperate with the adjustment mechanism 4, allowing the first mounting bracket 31 and the second mounting bracket 32 ​​to move up and down on the guide screws 5, thereby adjusting the height of the video acquisition mechanism 3.

[0029] Since the fixed base 21 is slidably connected to the base 1, when it is necessary to adjust the position of the movable frame 2 on the base 1, the fixed base 21 can be pushed or pulled to slide on the base 1, thereby changing the overall position of the movable frame 2 and providing a suitable horizontal position for subsequent video acquisition work.

[0030] When the height of the video acquisition mechanism 3 needs to be adjusted, the adjustment mechanism 4 is operated. The adjustment mechanism 4 may use mechanical transmission, electric drive, or other means to move the first mounting bracket 31 and the second mounting bracket 32 ​​up and down along the guide screw 5. The guide screw 5 provides a stable guide for the movement of the first mounting bracket 31 and the second mounting bracket 32, maintaining vertical linear motion during the movement. As the first mounting bracket 31 and the second mounting bracket 32 ​​move, the video acquisition components such as the camera 311 and the fill light 321 mounted on them will also move up and down accordingly, thereby adjusting the height of the video acquisition mechanism 3 to meet the needs of different shooting heights and angles.

[0031] Combination Figures 1-4 As shown, the adjustment mechanism 4 includes a fixed rod 41 mounted on a fixed base 21. The fixed rod 41 is internally threaded with a first threaded rod 42. The first threaded rod 42 passes through the first mounting bracket 31 and the second mounting bracket 32 ​​in sequence, perpendicular to the fixed base 21.

[0032] Specifically, the fixed rod 41 is mounted on the fixed base 21, providing a stable mounting foundation for the adjusting mechanism 4. The fixed rod 41 has an internal threaded structure, providing conditions for the connection and movement of the first threaded rod 42. The first threaded rod 42 is threadedly connected to the fixed rod 41, allowing it to rotate within the fixed rod 41 and move relatively vertically. The first threaded rod 42 passes perpendicularly to the fixed base 21, sequentially through the first mounting bracket 31 and the second mounting bracket 32. It not only connects the first mounting bracket 31 and the second mounting bracket 32 ​​but also, through its own movement, drives the height adjustment of the first mounting bracket 31 and the second mounting bracket 32.

[0033] When the height of the video acquisition mechanism 3 needs to be adjusted, the operator rotates the first threaded rod 42. Since the first threaded rod 42 is internally threaded to the fixed rod 41, according to the principle of threaded transmission, when the first threaded rod 42 rotates, it will move axially within the fixed rod 41.

[0034] If the first threaded rod 42 is rotated clockwise, it will move upward, causing the first mounting bracket 31 and the second mounting bracket 32 ​​to move upward along the first threaded rod 42, thereby increasing the overall height of the video acquisition mechanism 3. Conversely, if the first threaded rod 42 is rotated counterclockwise, it will move downward, causing the first mounting bracket 31 and the second mounting bracket 32 ​​to move downward, thereby decreasing the overall height of the video acquisition mechanism 3.

[0035] Combination Figures 1-4 As shown, an adjusting handwheel 421 is provided on the top of the first threaded rod 42.

[0036] Specifically, an adjusting handwheel 421 is specially provided at the top of the first threaded rod 42. The adjusting handwheel 421 is usually a circular or near-circular component with a certain diameter and thickness, and its outer edge may be designed with anti-slip textures or raised structures to facilitate the operator's gripping and rotation. The adjusting handwheel 421 is fixedly connected to the top of the first threaded rod 42. This connection method can be welding, threaded connection, etc., to ensure that the adjusting handwheel 421 and the first threaded rod 42 can rotate synchronously.

[0037] When the height of the video acquisition mechanism 3 needs to be adjusted, the operator holds the adjusting handwheel 421. Then, to raise or lower the video acquisition mechanism 3 as needed, the adjusting handwheel 421 is rotated clockwise or counterclockwise. Because the adjusting handwheel 421 is fixedly connected to the first threaded rod 42, rotating the adjusting handwheel 421 will drive the first threaded rod 42 to rotate synchronously.

[0038] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both the first mounting bracket 31 and the second mounting bracket 32 ​​are provided with threaded sleeves 7, and the first threaded rod 42 passes through the threaded sleeves 7 and is threadedly connected to the first mounting bracket 31 and the second mounting bracket 32.

[0039] Specifically, threaded sleeves 7 are provided on both the first mounting bracket 31 and the second mounting bracket 32. The threaded sleeve 7 is typically a hollow cylindrical component with threads machined on its inner wall to match the first threaded rod 42. The threaded sleeve 7 can be fixed to the first mounting bracket 31 and the second mounting bracket 32 ​​by welding, bolting, or other methods to ensure a stable and reliable connection between it and the mounting brackets.

[0040] The first threaded rod 42 is a key component for adjusting the height of the video acquisition mechanism 3. It passes perpendicularly to the fixed base 21 through the threaded sleeves 7 on the first mounting bracket 31 and the second mounting bracket 32, and is threadedly connected to the threaded sleeves 7. This allows the first threaded rod 42 to generate relative axial movement with the first mounting bracket 31 and the second mounting bracket 32.

[0041] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fill light 321 has a circular structure, and the camera 311 is located directly below the center of the fill light 321.

[0042] Specifically, the fill light 321 is integrally in a ring structure. The fill light 321 in the ring structure is usually composed of multiple light-emitting units (such as LED lamp beads) evenly distributed on the inner or outer side of the ring, forming a closed annular light source. The uniform distribution of the light-emitting units can ensure that light is emitted evenly from all directions, forming a relatively uniform illumination area. The fill light 321 is installed on the second mounting bracket 32, providing sufficient and uniform light for subsequent shooting work.

[0043] The camera 311 is set directly below the center of the fill light 321. The camera 311 is usually installed on the first mounting bracket 31, and its lens faces the area illuminated by the fill light 321. Setting the camera 311 directly below the center of the fill light 321 can ensure that the camera 311 is in the optimal illumination center position during shooting, making the most of the light provided by the fill light 321.

[0044] During shooting, the object to be photographed is in the central illumination area of the fill light 321, and the camera 311 can receive the most uniform and sufficient light. This enables the camera 311 to clearly capture the details and features of the object and collect high-quality images. The collected images are then sent to the detection terminal, which compares the collected images with the specified images to determine whether the object is qualified. This greatly improves the accuracy and reliability of image acquisition, and进而 improves the detection accuracy and efficiency of the entire visual detection system.

[0045] Combined Figures 1-4 As shown, a guiding groove 11 is provided on the base 1, and a guiding block 211 matching the guiding groove 11 is provided at the bottom of the fixing base 21. A driving mechanism 6 for driving it to slide on the base 1 is provided in the middle of the bottom of the fixing base 21.

[0046] Specifically, a guiding groove 11 is provided on the base 1, and the guiding groove 11 ensures a good match with the guiding block 211 at the bottom of the fixing base 21. The direction of the guiding groove 11 determines the sliding direction of the fixing base 21 on the base 1. Generally, according to actual working requirements, the guiding groove 11 can be linear, enabling the fixing base 21 to move linearly on the base 1.

[0047] A guiding block 211 matching the guiding groove 11 is provided at the bottom of the fixing base 21. The shape and size of the guiding block 211 are adapted to the guiding groove 11, and it can be embedded in the guiding groove 11 and slide along the guiding groove 11. The cooperation between the guiding block 211 and the guiding groove 11 plays a guiding role, ensuring that the fixing base 21 maintains a stable movement trajectory during sliding and avoiding situations such as shaking or deviation.

[0048] A drive mechanism 6 is provided at the bottom center of the fixed base 21. The drive mechanism 6 is the power source for the fixed base 21 to slide on the base 1. By connecting with the bottom of the fixed base 21, the power is transmitted to the fixed base 21 to enable it to slide.

[0049] The drive mechanism 6 generally includes a power source (such as a motor), transmission components (such as a lead screw and nut transmission assembly, a gear and rack transmission assembly, etc.), and connecting components. The power source provides driving force, the transmission components convert the power generated by the power source into linear motion of the fixed base 21, and the connecting components ensure a firm connection between the drive mechanism 6 and the bottom of the fixed base 21 for accurate power transmission. For example, if a lead screw and nut transmission assembly is used, the motor drives the lead screw to rotate, the nut is connected to the bottom of the fixed base 21, and when the lead screw rotates, the nut moves along the lead screw axis, thereby causing the fixed base 21 to slide.

[0050] Combination Figures 1-4 As shown, the drive mechanism 6 includes a sliding groove 61 disposed in the middle of the base 1, a drive motor 62 disposed inside the sliding groove 61, a second threaded rod 63 connected to the output end of the drive motor 62, a sliding block 212 disposed in the middle of the bottom of the fixed seat 21, a threaded hole disposed inside the sliding block 212, and the second threaded rod 63 passes through the threaded hole of the sliding block 212 and is threadedly connected to the fixed seat 21.

[0051] Specifically, a sliding groove 61 is provided in the middle of the base 1. The sliding groove 61 is a groove with a certain length, width and depth. Its function is to provide installation space and movement track for other components of the drive mechanism 6, so as to ensure that the drive mechanism 6 can work normally and drive the fixed seat 21 to slide.

[0052] The drive motor 62 is located inside the sliding groove 61 and serves as the power source for the drive mechanism 6. The drive motor 62 is mounted within the sliding groove 61 using bolts or other fixing methods, and its output end can output rotational power. The drive motor 62 facilitates precise control of the sliding position of the fixed base 21.

[0053] One end of the second threaded rod 63 is connected to the output end of the drive motor 62. When the drive motor 62 is working, it can drive the second threaded rod 63 to rotate. The length of the second threaded rod 63 is determined according to the length of the sliding groove 61 and the sliding stroke of the fixed seat 21. Its outer surface is machined with threads to cooperate with the threaded hole inside the sliding block 212 to realize threaded transmission.

[0054] A sliding block 212 is provided in the middle of the bottom of the fixed base 21. The sliding block 212 is a protruding structure that is adapted to the shape of the sliding groove 61 and can slide within the sliding groove 61. A threaded hole is provided inside the sliding block 212. The size and thread specification of the threaded hole match the second threaded rod 63, so that the second threaded rod 63 can pass through the threaded hole and be threadedly connected to the fixed base 21 (through the sliding block 212).

[0055] When it is necessary to drive the fixed base 21 to slide on the base 1, the drive motor 62 starts. The output end of the drive motor 62 starts to rotate, driving the second threaded rod 63 connected to it to rotate synchronously. Since the second threaded rod 63 passes through the threaded hole of the sliding block 212 and is threadedly connected to the fixed base 21 (through the sliding block 212), according to the principle of threaded transmission, when the second threaded rod 63 rotates, the sliding block 212 will move along the axial direction of the second threaded rod 63.

[0056] The movement of the sliding block 212 causes the fixed seat 21 to slide together on the base 1. Because the sliding block 212 slides within the sliding groove 61, the sliding groove 61 acts as a guide, ensuring that the sliding direction of the fixed seat 21 is stable and accurate, without any deviation or wobbling. By controlling the speed, direction, and running time of the drive motor 62, the sliding speed, direction, and displacement distance of the fixed seat 21 can be controlled, thereby achieving flexible adjustment of the position of the fixed seat 21 to meet the needs of different working scenarios.

[0057] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
