[0027] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0028] like Figure 1 As shown, a graphite electrode surface detection system of this application includes a detection stage 1, a guide rail sliding mechanism 2, a moving bracket 3, a detection probe fixing seat 4, and an optical calibration module 5. Through reasonable layout and structural design, it can achieve accurate scanning and detection of the graphite electrode surface.

[0029] The testing platform 1 is the fundamental support component of the system, used to support other parts of the entire testing system and ensure its overall stability. The testing platform 1 can be made of high-hardness cast iron or steel to ensure long-term reliability and durability. In actual manufacturing, the testing platform 1 can be precision machined to provide a flat and stable support surface.

[0030] The guide rail sliding mechanism 2 is mounted on the testing table 1 to guide the smooth movement of the testing device and effectively reduce the impact of vibration during high-speed testing. The guide rail sliding mechanism 2 contains a ball lubrication groove 21 (see details). Figure 2 The system significantly reduces resistance by replacing sliding friction with rolling friction; simultaneously, reinforcing ribs 22 are embedded in its frame to enhance structural rigidity; in addition, it is equipped with shock-absorbing elastic pads 23, which can effectively absorb high-frequency vibration energy. Technically, the shock absorption effect can be achieved by optimizing the surface precision of the ball bearing track and using high-quality rubber material to make the pads.

[0031] The movable bracket 3 is mounted on the upper part of the guide rail sliding mechanism 2 and achieves lateral or longitudinal position adjustment through a specific fit. This adjustment relies on the precise connection structure with the guide rail, allowing the bracket to move freely within a set track range, providing a precise operating platform for the detection probe. For example, the bracket can be firmly fixed in any selected position using a locking method with fine-tuning screws, facilitating the adjustment of positioning accuracy.

[0032] The probe holder 4 is designed to connect to the aforementioned movable bracket 3. Its function is to firmly clamp the probe and maintain its precise geometric orientation. This component contains a complex clamping mechanism that allows for quick replacement of probes of different sizes, while also considering the layout of electrical wiring to transmit signals to the data processor for analysis. For example, using a three-jaw chuck with electric tension control ensures both stability and improved operational efficiency.

[0033] The optical calibration module 5 is fixed to one side or end of the testing stage 1 and acts as a reference point for the spatial coordinate system. When other components accumulate errors due to temperature differences, expansion and contraction, wear, etc., the module can compare with this reference value to correct any angular deviations that may occur in the process in real time. The module itself may have a built-in light source emitting element and a reflector assembly to jointly construct the optical path, and combine the displacement parameters captured by the image sensor after the light returns to obtain the specific correction value.

[0034] To address the technical challenge of reducing vibration during high-speed testing, the guide rail sliding mechanism 2 employs a combination of measures: First, it incorporates ball bearing lubrication grooves 21, utilizing ball bearings instead of the traditional slider motion to significantly reduce friction caused by contact, thereby suppressing unstable vibrations. Second, several cross-distributed reinforcing ribs 22 are added to further stabilize the robotic arm structure and prevent deformation. Finally, flexible, shock-absorbing elastic pads 23 are tightly attached to the base to buffer instantaneous pressure impacts and prevent resonance. The combination of these methods ultimately achieves excellent noise reduction and vibration resistance, ensuring continuity and accuracy under high-speed conditions.

[0035] like Figure 2As shown, in one embodiment, the guide rail sliding mechanism 2 of the graphite electrode surface detection system of this application is provided with a multi-stage damping unit 24, which is located below the guide rail. This unit mainly consists of multiple layers of elastic material and a rigid support structure. The elastic material is used to initially absorb vibration energy, while the rigid support structure is responsible for limiting elastic deformation and ensuring overall stability. This layered design effectively and gradually attenuates vibrations generated during high-speed movement and protects the normal operation of other components. Specifically, the multi-stage damping unit 24 is tightly fitted into the space at the bottom of the guide rail and fixed to the detection stage 1 by high-strength adhesive or mechanical connection.

[0036] For example, the multi-stage damping unit 24 can be installed directly on the bottom of the guide rail using a layer of rubber pad as the primary damping material, while a reinforcing frame made of steel plate is superimposed on its lower end to distribute the load force, and finally it is securely fixed to the test bench 1 with bolts. This method not only facilitates assembly and adjustment, but also flexibly adapts to the vibration requirements of different working environments.

[0037] like Figure 2 As shown, in one embodiment, the ball bearing lubrication groove 21 of the graphite electrode surface detection system of this application is equipped with an automatic lubricating oil replenishment device 25 to ensure that the frictional resistance in the guide rail sliding mechanism 2 remains at a low level during long-term operation. This device is installed on one side of the internal space of the ball bearing lubrication groove 21 and connected to an oil reservoir via a precision pipeline, thereby achieving continuous lubricating oil replenishment. Specifically, the automatic lubricating oil replenishment device 25 includes a micro pump, a flow sensor, and a control unit, which work together to complete the automatic replenishment process. Furthermore, its structural design fully considers installation space limitations and ease of maintenance; therefore, the entire device is embedded in the guide rail sliding mechanism 2 without affecting the overall layout.

[0038] In one embodiment, the automatic lubricating oil replenishment device 25 includes a micro-pump disposed within the ball bearing lubrication groove 21, and a flow sensor monitors the lubricating oil flow rate in real time, ensuring accurate and stable replenishment. Specifically, the device's control unit receives data feedback from the sensor and drives the micro-pump to operate as needed, thereby achieving dynamic management of the lubricating oil.

[0039] like Figure 3As shown, in one embodiment, a reinforcing rib 22 of the graphite electrode surface inspection system of this application is disposed inside the guide rail sliding mechanism 2, which plays a role in improving the overall structural rigidity. The cross-section of the reinforcing rib 22 is designed as an I-shaped structure. Through this geometric characteristic, the bending strength of the component is significantly improved while maintaining material savings. In addition, the I-shaped structure design can optimize the load transmission path, ensuring that the structure is not easily deformed under external loads and dynamic impacts, thereby enhancing the stability of the system. As a key component of the system, the reinforcing rib 22 is closely matched with the guide rail sliding mechanism 2, installed close to the upper part of the inspection table 1, and distributed around the ball lubrication groove 21, further improving the overall assembly accuracy.

[0040] For example, by controlling the forming process of the I-shaped reinforcing rib 22 during manufacturing, such as by selecting press molding or precision casting, high geometric accuracy can be achieved. Specifically, this component is assembled into the guide rail sliding mechanism 2 by bonding, welding, or tight-fitting to form a stable overall structure. This installation method ensures the functionality of the reinforcing rib 22 while facilitating assembly and maintenance.

[0041] In one embodiment, the shock-absorbing elastic pad 23 of the graphite electrode surface inspection system of this application adopts a layered composite material structure design. The shock-absorbing elastic pad 23 is located at the bottom of the guide rail sliding mechanism 2, and is used to buffer and absorb vibrations generated by system operation, thereby ensuring stability during the inspection process. The outer layer is made of soft silicone, which has good wear resistance and softness to reduce interference from external impacts on the system. The inner layer uses high-strength polyurethane foam as the main load-bearing material, which can effectively disperse pressure and provide the necessary elastic recovery capability for the overall structure.

[0042] For example, the shock-absorbing elastic pad 23 can be fixed to the connection position between the guide rail sliding mechanism 2 and the detection table 1 by adhesive bonding or nesting. Its manufacturing process can involve injection molding soft silicone onto the periphery of high-strength polyurethane foam to form a strong layered bond. Specifically, to ensure the bonding strength between the materials, surface activation treatment can be used to enhance the interface fusion effect, while pre-reserving installation interfaces for precise assembly. In this way, the shock-absorbing elastic pad 23 can optimize vibration transmission characteristics without affecting the system rigidity.

[0043] like Figure 1As shown, in one embodiment, the detection stage 1 of the graphite electrode surface detection system of this application is provided with an embedded counterweight module 6. The counterweight module is placed in the lower part of the detection stage 1 or within a structure near its bottom, and is integrated with the detection stage 1 through a tight installation. This installation method not only helps to improve the overall center of gravity stability of the system, but also effectively reduces the risk of resonance caused by high-speed rotating components. Furthermore, the counterweight module can be made of high-density materials, such as lead alloys or special steel, and its size and shape can be adjusted according to specific working conditions to meet different weight distributions and rigidity requirements.

[0044] The embedded counterweight module 6 is designed with a balance between system vibration characteristics and load-bearing capacity in mind. Its external contour conforms to the internal shape of the testing platform 1, and its interior may feature uniform partitions to allow for the addition or replacement of materials in localized areas, further optimizing mass distribution. Specifically, the module can be fixed to pre-drilled holes in the testing platform 1 using fasteners or directly molded into an integral form with the testing platform 1, ensuring a stable connection during long-term use. For example, in a practical scenario, a hybrid assembly method combining high-strength adhesives and bolts can securely embed the counterweight module into the main frame of the testing platform 1, preventing displacement or loosening due to external impacts.

[0045] like Figure 4 As shown, in one embodiment, a dynamic balancer 7 is provided inside the movable support 3 of the graphite electrode surface detection system of this application. The dynamic balancer 7 suppresses vibrations generated during high-speed movement through a special reverse inertia adjustment structure. Specifically, the dynamic balancer 7 is installed in the central region of the movable support 3, maintaining a tight connection with the entire movable support 3, and its outer shell is fixed to the inside of the movable support 3 by fasteners or an embedded design, thereby ensuring structural stability and reliability. In terms of composition, the dynamic balancer 7 includes an active counterweight unit and a reverse drive mechanism. The former is responsible for simulating external vibration forces, while the latter is used to generate equal-amplitude reverse forces to counteract the vibration effects.

[0046] For example, a servo motor equipped with a precision encoder can be used as the core component. The servo motor drives the active counterweight unit to rotate and adjusts the speed in real time according to a set algorithm to generate the required inertial feedback to match the vibration frequency during high-speed movement. In this way, the operational stability of the entire detection system is significantly improved, while ensuring that the detection accuracy is not affected by external interference.

[0047] like Figure 1As shown, in one embodiment, the optical calibration module 5 of the graphite electrode surface inspection system of this application is connected to the leveling base 8 via a specific fixing method, and the leveling base 8 is mounted on the inspection stage 1. This design ensures that the system can accurately calibrate the positional deviation of the inspection probe in complex working environments. Specifically, the leveling base 8 is located at one end of the inspection stage 1 and serves as the interface between the optical calibration module 5 and the entire system, providing support and adjustment. Furthermore, the leveling base 8 contains a height fine-tuning mechanism, which can achieve millimeter-level or even sub-millimeter-level height difference adjustment through precision thread engagement. Therefore, in the event of environmental vibration or slight equipment tilt, the error caused by mechanical deformation can be compensated by adjusting the height difference, thereby improving inspection accuracy.

[0048] In one embodiment, the optical calibration module 5 is secured to the upper surface of the leveling base 8 by several high-strength bolts. The leveling base 8 is mounted on the testing table 1 in a planar connection manner, and its bottom is equipped with an elastic pad to absorb the vibration caused by external forces. Technically, this fine-tuning function relies on a built-in handwheel drive device, which rotates a screw to complete the height adjustment, thereby optimizing calibration performance and maintaining the system's vibration resistance.

[0049] like Figure 4 As shown, in one embodiment, the guide rail sliding mechanism 2 of the graphite electrode surface detection system of this application is equipped with buffer stop components 9 at both ends. These components are mainly used to prevent impact problems caused by high speed or inertia when the moving support 3 stops at the end of the guide rail sliding mechanism 2, thereby effectively isolating the impact force on the overall system. The buffer stop components 9 are fixed to both ends of the guide rail sliding mechanism 2 through a connecting structure. Their design ensures that the linear accuracy of the guide rail sliding mechanism 2 is not affected during contact with the support, while simultaneously achieving good shock absorption.

[0050] Specifically, the buffer stop assembly 9 can be composed of a composite of elastic material and a metal frame, where the elastic part is responsible for absorbing impact energy, while the metal frame is used to enhance the overall strength and stability of the assembly. This assembly is installed onto the testing table 1 using bolts or other fasteners, ensuring that its outer edge is slightly higher than the port plane of the guide rail sliding mechanism 2. When the moving bracket 3 reaches the end of the guide rail, its end will be the first to contact the front surface of the buffer stop assembly 9.

[0051] For example, the degree of impact absorption can be controlled by adjusting the spring preload within the buffer stop assembly 9 to adapt to the needs of different operating speeds. This combination ensures that the system maintains long-term reliability even under high-frequency or wide-range motion conditions.

[0052] In actual operation, when this device is used, the graphite electrode is placed on the support surface of the detection stage 1, and then the guide rail sliding mechanism 2 is activated. This mechanism guides the moving bracket 3 to move smoothly along the guide rail direction. The ball bearing lubrication groove 21 reduces frictional resistance, while the reinforcing ribs 22 increase structural rigidity and the shock-absorbing elastic pads 23 absorb vibration to ensure the stability of high-speed detection. The detection probe fixing seat 4 on the moving bracket 3 is used to firmly clamp the detection probe and ensure its precise position, thereby scanning and detecting the surface of the graphite electrode. During this process, the optical calibration module 5 provides a reference coordinate system to assist in correcting any positional deviations that may occur in the detection probe, ensuring that the measurement results of the entire detection system have high accuracy.
