Description

Technical Field

[0001] This utility model relates to the field of mold inspection technology, specifically a mold processing surface quality inspection device. Background Technology

[0002] Molds play a crucial role in industrial production, and their surface quality directly affects the molding accuracy, surface finish, and lifespan of the product. With the continuous development of the manufacturing industry, the requirements for the surface quality of mold processing are increasing. However, current mold processing surface quality testing devices on the market have many problems.

[0003] Traditional inspection methods, such as manual visual inspection, rely primarily on the experience and visual observation of the mold surface by inspectors. This method is highly subjective and easily affected by factors such as inspector fatigue and eyesight, making it difficult to detect minute defects. Furthermore, its low efficiency cannot meet the demands of large-scale production. Some methods using simple measuring tools can only measure the mold's dimensions to a limited extent, failing to comprehensively assess surface roughness, flatness, scratches, cracks, and other quality issues. For molds with complex shapes, the use of measuring tools is severely limited, making it difficult to accurately obtain quality data for critical areas.

[0004] While some existing camera-based inspection devices can perform a certain degree of inspection on the mold surface through image acquisition, most of them use a single or multiple cameras in fixed positions. Therefore, in actual inspection, blind spots will be generated in the inspection of the mold surface, making it impossible to achieve all-round inspection. As a result, some quality problems in key areas are easily missed, which in turn affects the overall judgment of the mold surface quality. Utility Model Content

[0005] The purpose of this invention is to provide a surface quality inspection device for mold processing, so as to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A surface quality inspection device for mold processing includes an inspection platform with a support rod mounted on its side. The support rod supports a drive platform. The bottom surface of the drive platform has a cavity, within which a first drive component and a second drive component are disposed. A protective box is located below the drive platform. The first drive component drives the protective box to move laterally, and the second drive component drives the protective box to move longitudinally. A mounting groove is formed on the bottom surface of the protective box, within which a detection probe is embedded. The top surface of the inspection platform has a cavity, within which a placement plate slides. A third drive component is disposed inside the inspection platform, driving the placement plate to move vertically. The first and second drive components enable the lateral and longitudinal movement of the detection probe in the horizontal plane. By coordinating with the third drive component to adjust the height of the placement plate, all areas of the mold surface can be fully covered, eliminating blind spots and ensuring clear and complete image information, thus improving the accuracy of the inspection results. The protective box protects the detection probe from external interference, ensuring inspection stability.

[0008] Furthermore, the first driving component includes a first connecting frame mounted on the top surface of the cavity. A first threaded rod is connected to the inside of the first connecting frame via a bearing. A first slider is threadedly engaged with the outer side of the first threaded rod. The first slider slides within the first connecting frame. A first motor is provided on the outer side of the driving platform, and the output end of the first motor is connected to the first threaded rod via a transmission connection. The threaded transmission between the first threaded rod and the first slider has high precision characteristics, which can realize precise control of the lateral movement of the protection box, ensure that the detection probe moves stably along the preset trajectory, and avoid missed detections or repeated detections.

[0009] Furthermore, the second driving component includes a second connecting frame located within the cavity, and the first and second connecting frames form a cross shape. A second threaded rod is connected to the interior of the second connecting frame via a bearing, and a second slider is threadedly connected to the outer side of the second threaded rod. The second slider slides within the second connecting frame. A second motor is provided on the outer side of the driving platform, and the output end of the second motor is connected to the second threaded rod. The second connecting frame is connected to the first slider, and the protective box is connected to the second slider. The cross-shaped distribution of the first and second connecting frames ensures that lateral and longitudinal movements do not interfere with each other. The transmission between the second threaded rod and the second slider makes the longitudinal movement of the protective box precise and controllable, and, in conjunction with the lateral movement, forms a complete horizontal scanning trajectory, achieving all-round coverage of the mold surface.

[0010] Furthermore, the side of the drive platform is provided with a sliding groove, and the connection between the output end of the second motor and the second threaded rod slides in the sliding groove. The sliding groove provides lateral sliding space for the connection between the second motor and the second threaded rod, ensuring that when the second connecting frame moves laterally with the first slider, the power of the second motor can be stably transmitted to the second threaded rod, avoiding jamming or damage to the transmission structure.

[0011] Furthermore, the drive platform is provided with a first protective cover and a second protective cover on its outer side. The first motor and the second motor are respectively installed inside the first protective cover and the second protective cover via a frame. The first protective cover is connected to the drive platform, and the second protective cover is connected to the second connecting frame. The outer sides of the first protective cover and the second protective cover are provided with heat dissipation slots. The protective covers can prevent dust and moisture, avoid damage to the motor due to external environmental influences, and extend the service life. The heat dissipation slots dissipate the heat generated by the generator during operation through air convection, preventing the motor from overheating and causing performance degradation or burnout.

[0012] Furthermore, a ring-shaped shadowless light source is installed on the bottom surface of the protective box, and the lens of the detection probe and the ring-shaped shadowless light source are arranged coaxially. The ring-shaped shadowless light source provides uniform and soft illumination, eliminates shadows and reflections on the mold surface, ensures that the detection probe can clearly capture surface details, and improves image contrast and detection accuracy.

[0013] Furthermore, the testing platform has a fixed cavity communicating with the cavity body. An electric telescopic rod is installed inside the fixed cavity. A support frame is installed on the bottom surface of the placement plate. The telescopic end of the electric telescopic rod is connected to the center of the support frame. The electric telescopic rod drives the placement plate to move vertically, which can quickly adjust the mold to the optimal focusing distance of the testing probe. The support frame ensures that the placement plate is subjected to uniform force, avoiding tilting of the mold during placement and affecting the testing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the mold processing surface quality inspection device realizes the horizontal and vertical movement of the inspection probe in the horizontal plane through the first and second driving components, and adjusts the height of the placement plate with the third driving component, which can fully cover all areas of the mold surface, eliminate blind spots, ensure the acquisition of clear and complete image information, and improve the accuracy of the inspection results; the protective box protects the inspection probe from external interference and ensures the stability of the inspection.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a mold processing surface quality inspection device, including an inspection table 1, a vertical rod 2 mounted on the side of the inspection table 1, the vertical rod 2 supporting a drive table 3, the bottom surface of the drive table 3 having a cavity, a first drive component and a second drive component being provided in the cavity, a protective box 7 being provided below the drive table 3, the first drive component driving the protective box 7 to move laterally, the second drive component driving the protective box 7 to move longitudinally, the bottom surface of the protective box 7 having an installation groove, the installation groove having an embedded inspection probe, the top surface of the inspection table 1 having a cavity 16, a placement plate 19 sliding inside the cavity 16, a third drive component being provided inside the inspection table 1, the third drive component driving the placement plate 19 to move vertically, the mold to be inspected being placed on the placement plate 19, the first drive component driving the protective box 7 to move laterally, the second drive component driving it to move longitudinally, so that the inspection probe can scan different positions on the mold surface; the third drive component adjusts the height of the placement plate 19 to change the distance between the mold and the inspection probe, ensuring that the probe is at the optimal imaging focal length, thereby clearly capturing details such as roughness, scratches, and cracks on the mold surface.

[0023] Specifically, the detection probe is usually a high-definition industrial camera or a 3D scanning probe. The image data it acquires is transmitted to an external control system (such as a computer) in real time. The system processes the image using image recognition algorithms (such as edge detection, grayscale analysis, feature extraction, etc.) to quantitatively evaluate various quality parameters of the mold surface (such as roughness Ra value, scratch depth, crack length, etc.). The system compares the analysis results with preset quality standards, automatically determines whether there are defects exceeding the standard on the mold surface, marks the location and type of defects, and finally generates an inspection report, realizing automated and high-precision inspection of the mold surface quality.

[0024] As an embodiment of this utility model, the first driving component further includes a first connecting frame 5 installed on the top surface of the cavity. A first threaded rod 12 is connected to the inside of the first connecting frame 5 through a bearing. A first slider 13 is threadedly engaged with the outer side of the first threaded rod 12. The first slider 13 slides within the first connecting frame 5. A first motor is provided on the outer side of the driving platform 3, and the output end of the first motor is connected to the first threaded rod 12. The first motor drives the first threaded rod 12 to rotate. The first slider 13 slides laterally within the first connecting frame 5 due to the thread engagement, thereby driving the second connecting frame 6 and the protective box 7 connected thereto to move synchronously, thereby realizing the lateral position adjustment of the detection probe.

[0025] As an embodiment of this utility model, the second driving member further includes a second connecting frame 6 located in the cavity, and the first connecting frame 5 and the second connecting frame 6 form a cross shape. The interior of the second connecting frame 6 is connected to a second threaded rod 14 through a bearing. The outer side of the second threaded rod 14 is threadedly connected to a second slider 15. The second slider 15 slides within the second connecting frame 6. A second motor is provided on the outer side of the driving platform 3, and the output end of the second motor is connected to the second threaded rod 14. The second connecting frame 6 is connected to the first slider 13, and the protective box 7 is connected to the second slider 15. The second motor drives the second threaded rod 14 to rotate, and the second slider 15 slides longitudinally within the second connecting frame 6, thereby driving the protective box 7 and the detection probe to move longitudinally. Since the second connecting frame 6 is connected to the first slider 13, it can move laterally synchronously with the first slider 13, thereby realizing the adjustment of the detection probe at any position in the horizontal plane.

[0026] As an embodiment of this utility model, the side of the drive platform 3 is provided with a sliding groove 4. The output end of the second motor and the connection of the second threaded rod 14 slide in the sliding groove 4. When the first slider 13 drives the second connecting frame 6 to move laterally, the second motor moves synchronously with the second connecting frame 6, and the connection between its output end and the second threaded rod 14 slides in the sliding groove 4 to maintain the continuity and stability of the power transmission.

[0027] As an embodiment of this utility model, the drive platform 3 is further provided with a first protective cover 9 and a second protective cover 10 on its outer side. The first motor and the second motor are respectively installed inside the first protective cover 9 and the second protective cover 10 through a frame. The first protective cover 9 is connected to the drive platform 3, and the second protective cover 10 is connected to the second connecting frame 6. The outer side of the first protective cover 9 and the second protective cover 10 are provided with heat dissipation grooves 11. The first protective cover 9 is fixed on the drive platform 3 to protect the first motor; the second protective cover 10 moves with the second connecting frame 6 to protect the second motor; the heat dissipation grooves 11 allow the heat generated by the motor to be dissipated in time, maintaining the motor operating temperature within the normal range.

[0028] As an embodiment of this utility model, the bottom surface of the protective box 7 is further equipped with a ring-shaped shadowless light source 8, and the lens of the detection probe and the ring-shaped shadowless light source 8 are arranged coaxially. The ring-shaped shadowless light source 8 surrounds the lens of the detection probe, and the light shines on the mold surface from multiple directions, avoiding uneven brightness caused by a single light source, making the defects on the mold surface easier to identify in the image, and facilitating subsequent analysis and processing.

[0029] As an embodiment of this utility model, the inside of the detection stage 1 is provided with a fixed cavity 17 that communicates with the cavity 16. An electric telescopic rod 18 is installed inside the fixed cavity 17. A support frame 20 is installed on the bottom surface of the placement plate 19. The telescopic end of the electric telescopic rod 18 is connected to the center of the support frame 20. When the electric telescopic rod 18 extends or retracts, it drives the placement plate 19 to slide up and down in the cavity 16 through the support frame 20, changing the vertical distance between the mold and the detection probe, ensuring that the image captured by the probe is clear and sharp, and meeting the resolution requirements of surface quality detection.

The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
