Description

Technical Field

[0001] This application relates to the field of metallurgical temperature measuring device technology, and in particular to a protective plug that can be installed on the temperature measuring connector of a measuring gun, and a disassembly and assembly device that can automatically install the protective plug onto the temperature measuring connector and automatically remove the protective plug from the temperature measuring connector. Background Technology

[0002] The temperature and composition of molten steel have a significant impact on the quality of the final steel products. Therefore, molten steel temperature measurement and sampling is a very important operation in the metallurgical industry, which directly affects the efficiency and quality of steel production. It is one of the key steps to ensure the stable operation and technological progress of the steel industry.

[0003] The molten steel temperature sampling station in steel plants is mostly a "three-high" environment, namely, high temperature, high dust, and high risk. In traditional production practice, temperature sampling is usually carried out manually. In specific operations, two probes are used, one for temperature measurement and the other for sampling. The operator holds the probe and inserts it into the surface of the molten steel to perform temperature measurement and sampling.

[0004] With the development of industrial automation, to protect personnel safety, reduce labor intensity, and improve the success rate and accuracy of temperature sampling, most steel plants have adopted temperature sampling robots to replace manual temperature sampling operations. There are generally two technical approaches to robotic temperature sampling: First, an industrial six-axis robot carries a single sampling gun. First, a temperature probe is installed for measurement, then the discarded probe is removed and a sampling probe is installed for sampling. In this approach, the robot uses the same sampling gun for temperature sampling. Second, an industrial six-axis robot equipped with a quick-change tool switches between two sampling guns to perform temperature sampling operations separately.

[0005] The above-mentioned route 1 has the following defects: the technical route of using the same probe for temperature measurement and sampling is as follows: when the sampling probe is inserted into the molten steel for sampling, the tar produced by the burning of the paper tube of the sampling probe will contaminate the temperature measuring connector along the probe hole, causing the surface of the temperature measuring connector to be covered with tar. The contact resistance of the connector will change, which will eventually lead to inaccurate temperature measurement data.

[0006] The above-mentioned Route 2 has the following drawbacks: The technical route of configuring quick-change tools to switch between two probes for temperature measurement and sampling requires two robot probes, two sets of quick-change tools, and probe storage racks, which not only occupies a large space in the temperature measurement and sampling station, but also has a high configuration cost.

[0007] Therefore, current robotic temperature measurement and sampling methods suffer from inaccurate temperature data, high space requirements, and high costs. It is necessary to propose a new technical solution to address these problems. Utility Model Content

[0008] This application provides a temperature measuring connector protective plug, a measuring gun, and a device for disassembling and assembling the plug, in order to solve the problem of inaccurate temperature measurement data in current robotic temperature sampling.

[0009] To achieve the above objectives, this application provides the following technical solution:

[0010] In the first aspect, this application provides a protective plug for a temperature measuring connector, including a plug body. One end of the plug body is provided with a conical structure for fitting and inserting into the housing of the temperature measuring connector. The conical structure includes a cone, the outer wall of which is press-fitted with the inner edge of the housing of the temperature measuring connector. The outer diameter of the cone near the temperature measuring connector is smaller than the outer diameter of the other end away from the temperature measuring connector.

[0011] Furthermore, in the above technical solution, a slot can be provided on the conical outer wall of the cone, and the slot is adapted to be inserted into the protrusion on the inner edge of the housing of the temperature measuring connector.

[0012] Secondly, this application provides a measuring gun equipped with the aforementioned temperature measuring connector protective plug, including a gun rod, one end of which is provided with a temperature measuring connector, and the end of the temperature measuring connector facing away from the gun rod is detachably connected to the temperature measuring connector protective plug.

[0013] Thirdly, this application provides a disassembly and assembly device for the aforementioned temperature measuring connector protective plug, including a base plate and a guide mechanism, a clamping mechanism, and a gripper mechanism mounted on the base plate; the guide mechanism includes a guide block with a guide hole forming an insertion channel for the measuring gun; the clamping mechanism includes a clamping component and a positioning detection component, the clamping component including a fixed base fixed on the base plate and a trigger rod passing through the fixed base, one end of the trigger rod being fitted with a spring between it and the plate surface of the fixed base, and the other end of the trigger rod passing through the fixed base and spaced relative to the limit switch of the positioning detection component, the guide hole being spaced relative to the trigger rod; the gripper mechanism includes a first gripper and a second gripper arranged opposite to each other, the first gripper and the second gripper being drivable to approach each other to clamp and hold the temperature measuring connector protective plug between the guide hole and the trigger rod.

[0014] Furthermore, in the above technical solution, the guide block has a frustum-shaped structure, the central axis of the guide hole coincides with the central axis of the guide block, and the guide hole is a through hole opened on the guide block; a fixing block is provided at the bottom of the guide block, and the guide block is fastened to the substrate through the fixing block.

[0015] Furthermore, the end of the probe with the temperature-sensing connector protrudes from the guide hole through the guide block and moves toward the temperature-sensing connector protective plug held by the gripper mechanism, so that the temperature-sensing connector and the temperature-sensing connector protective plug are inserted into each other. The first and second grippers are driven to move away from each other to release the temperature-sensing connector protective plug. The probe, carrying the temperature-sensing connector protective plug, continues to move toward the trigger rod. After the temperature-sensing connector protective plug is pressed against the trigger rod, the spring is compressed and the trigger rod is driven to move toward the limit switch and trigger the limit switch. The probe stops moving forward, and the temperature-sensing connector and the temperature-sensing connector protective plug are securely inserted.

[0016] Furthermore, the probe gun with the protective plug for the temperature measuring connector installed at the end passes through the guide hole and out of the guide block. The protective plug for the temperature measuring connector abuts against the trigger rod and compresses the spring, causing the trigger rod to trigger the limit switch. The first and second grippers are driven to move closer to each other to hold the protective plug for the temperature measuring connector. The probe gun retracts along the guide hole to remove the protective plug for the temperature measuring connector from the temperature measuring connector.

[0017] Furthermore, an arc-shaped groove is provided at the end of the first gripper facing the second gripper, and an arc-shaped groove is provided at the end of the second gripper facing the first gripper. The two arc-shaped grooves are respectively adapted and snapped into the side wall of the temperature measuring connector protective plug. Anti-slip pads or anti-slip textures are provided on the groove wall of the arc-shaped groove.

[0018] Furthermore, the testing gun can be inserted into the guide hole and move along the guide hole under the drive of the industrial robot; the control system on the industrial robot is connected to the limit switch signal.

[0019] Compared with the prior art, this application has at least the following beneficial effects:

[0020] 1. Based on further analysis and research of existing technical problems, this application recognizes that when the same probe is used for temperature measurement and sampling in current robotic systems, the tar generated during the sampling operation of the sampling probe into molten steel can contaminate the temperature measurement connector along the probe hole, causing the surface of the connector to be covered with tar. This alters the connector's contact resistance and ultimately leads to inaccurate temperature measurement data. Therefore, this application provides a protective plug for the temperature measurement connector. This protective plug can be detachably connected to the temperature measurement connector. After the robotic probe has completed temperature measurement and removed the used probe, the protective plug can be installed on the temperature measurement connector before the sampling probe is installed for sampling. This avoids tar contamination of the temperature measurement connector during sampling, ensuring the performance of the temperature measurement connector and guaranteeing accurate temperature measurement data.

[0021] 2. Based on the protective plug for the temperature measuring connector provided above, this application also provides a measuring gun that can perform temperature measurement and sampling operations. The temperature measuring connector of the measuring gun is provided with a protective plug, which is detachably connected to the temperature measuring connector. When using the measuring gun to measure temperature, a temperature measuring probe is installed on the temperature measuring connector. After the temperature measurement is completed, the waste temperature measuring probe is removed, and the protective plug is installed on the temperature measuring connector. Then, the sampling probe is installed to perform the sampling operation. This avoids the temperature measuring connector being contaminated during the sampling operation, which would lead to unreliable temperature measurement data. Compared with the traditional scheme of using two measuring guns to perform temperature measurement and sampling separately, this application uses the same gun to complete the temperature measurement and sampling operations sequentially. This can significantly reduce the configuration cost and space occupation of the robot measuring gun while ensuring the accuracy of temperature measurement, and effectively solve the problem of narrow space at the temperature measurement and sampling station and the difficulty in deploying temperature measurement and sampling robots.

[0022] 3. This application also provides a device for disassembling and assembling a protective plug for a temperature measuring connector, which includes a guide mechanism, a clamping mechanism, and a gripper mechanism integrated on a substrate. The guide mechanism includes a guide block with a guide hole, mainly for guiding the measuring gun into the disassembly and assembly device. The clamping mechanism includes a fixed base fixed on the substrate and a trigger rod passing through the fixed base. A spring is provided between one end of the trigger rod and the surface of the fixed base, and the other end of the trigger rod is spaced apart from a limit switch. The guide hole is spaced apart from the trigger rod. The gripper mechanism includes a first gripper and a second gripper arranged opposite to each other. The first gripper and the second gripper can be driven to approach each other to clamp and hold the protective plug for the temperature measuring connector between the guide hole and the trigger rod. Therefore, when using this disassembly and assembly device to install the protective plug, the gripper mechanism can first clamp and hold the protective plug in the target position, and then the robot can carry the measuring gun through the plate. After the guide block and protective plug are connected, the gripper mechanism releases the probe after the probe is connected to the protective plug. The probe continues to move forward until the limit switch is triggered, indicating that the temperature measuring connector and the protective plug are securely connected. The probe stops moving forward, the protective plug installation is complete, and the robot can remove the probe from the disassembly and assembly device. Then, a sampling probe is installed on the protective plug for sampling. After the sampling operation is completed, the robot removes the sampling probe and carries the probe to the disassembly and assembly device. The gripper mechanism holds the protective plug, and then the robot moves the probe backward to remove the protective plug. Therefore, the disassembly and assembly device provided in this application can automatically install the protective plug onto the temperature measuring connector and automatically remove the protective plug from the temperature measuring connector, thus protecting the temperature measuring connector and enabling the same probe to complete temperature measurement and sampling operations sequentially. This avoids the problem of unreliable temperature measurement data caused by contamination of the temperature measuring connector during the sampling operation. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0031] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to facilitate intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationships in the actual product. Changes in these relative positional relationships, without departing from the technical concept disclosed in this application, should also be considered within the scope of this application.

[0032] Example 1

[0033] To address the problems existing in the prior art, this application provides a protective plug 1 for a temperature measuring connector, including a plug body. One end of the plug body is provided with a conical structure for fitting and inserting into the outer shell of a temperature measuring connector 2. The conical structure includes a conical cylinder, the outer wall of which is press-fitted with the inner edge of the outer shell of the temperature measuring connector. The outer diameter of the end of the conical cylinder near the temperature measuring connector 2 is smaller than the outer diameter of the end away from the temperature measuring connector 2. A schematic diagram of the structure of installing the protective plug 1 on the temperature measuring connector 2 is shown below. Figure 3 .

[0034] In other embodiments, a slot can be provided on the conical outer wall of the above-mentioned conical structure, and the slot can be fitted and plugged into the protrusion on the inner edge of the housing of the temperature measuring connector 2. The two are interference fit to ensure reliable connection.

[0035] It should be noted that the cone in this application can be a cone-shaped columnar structure with sloping side walls, such as a frustum of a cone, a square frustum, or a pentagonal frustum.

[0036] The protective plug in this application is made of high-temperature resistant material. One end of it is plugged into the temperature measuring connector, and the other end can be connected to the sampling probe. Setting the connection between the protective plug and the temperature measuring connector as a plug-in connection facilitates installation and disassembly. Alternatively, the connection between the protective plug and the temperature measuring connector can be set as a threaded connection. With this connection structure, the probe needs to rotate during forward or backward movement, and this rotation can be accomplished by a robot carrying the probe.

[0037] The protective plug 1 for the temperature measuring connector in this application can be of other structural forms, materials or other connection methods, as long as it can isolate the temperature measuring connector from the tar generated by the combustion of the sampling probe.

[0038] Therefore, the protective plug 1 of the temperature measuring connector provided in this application can be detachably connected to the temperature measuring connector 2. After the robot measuring gun has completed the temperature measurement and removed the waste temperature measuring probe, the protective plug can be installed on the temperature measuring connector, and then the sampling probe can be installed to perform the sampling operation. This can avoid the tar generated during the sampling operation from contaminating the temperature measuring connector, ensure the performance of the temperature measuring connector, and ensure the accuracy of the temperature measurement data.

[0039] Example 2

[0040] This application provides a measuring gun, which includes a gun barrel. A temperature measuring connector 2 is provided at one end of the gun barrel. The end of the temperature measuring connector 2 facing away from the gun barrel is detachably connected to the temperature measuring connector protective plug 1 disclosed in Embodiment 1.

[0041] When using this temperature measuring gun for temperature measurement, a temperature probe is installed on the temperature measuring connector. After the temperature measurement is completed, the discarded temperature probe is removed, and a protective plug is installed on the temperature measuring connector. Then, the sampling probe is installed to perform the sampling operation. This avoids contamination of the temperature measuring connector during the sampling operation, which would lead to unreliable temperature measurement data. Compared with the traditional scheme of using two measuring guns to perform temperature measurement and sampling separately, this application uses the same gun to complete the temperature measurement and sampling operations sequentially. This can significantly reduce the configuration cost and space occupation of the robot measuring gun while ensuring the accuracy of temperature measurement. It also effectively solves the problem of narrow space at the temperature measurement and sampling station and the difficulty in deploying the temperature measurement and sampling robot.

[0042] Therefore, the probe provided in this application solves the problem of tar contamination of the temperature measurement connector caused by the use of a single probe for temperature sampling in robots. Furthermore, while ensuring the accuracy of temperature measurement, it reduces the cost of the robot probe by 50% and the space occupied by the robot probe installation by 50%, effectively improving the problem of difficult spatial layout of temperature sampling robots.

[0043] Example 3

[0044] This application provides a device for disassembling and assembling a protective plug 1 for a temperature measuring connector, which includes a guide mechanism, a clamping mechanism, and a gripper mechanism integrated on a substrate 3.

[0045] See Figure 1 , 2 The aforementioned guiding mechanism includes a guide block 4, on which a guide hole is provided, primarily to guide the measuring gun into the disassembly and assembly device. In this embodiment, the guide block 4 is preferably a frustum-shaped structure, but it can also be a truncated pyramidal structure with any number of sides. The sidewalls of this frustum-shaped or truncated pyramidal structure form a certain cone angle, thus allowing the provision of a guide cone surface and a guide hole. This effectively solves the problem of being unable to install the temperature measuring connector protective plug 1 due to slight bending deformation of the measuring gun.

[0046] The aforementioned clamping mechanism mainly includes a clamping component and a positioning detection component. The clamping component includes a fixed base 5 fixed on the base plate 3 and a trigger rod 6 passing through the fixed base 5. A spring 7 is provided between one end of the trigger rod 6 and the plate surface of the fixed base 5. The other end of the trigger rod 6 is spaced apart from the limit switch 8 of the positioning detection component. The guide hole is spaced apart from the trigger rod 6. The trigger rod 6 and the spring 7 can not only assist in clamping the protective plug, but also detect whether the protective plug is installed or removed in place when the limit switch 8 is triggered. When the test gun retracts and resets, the spring 7 can also drive the trigger rod 6 to automatically spring back and reset.

[0047] The aforementioned gripper mechanism mainly includes a first gripper 9 and a second gripper 10 arranged opposite to each other, such as... Figure 1The first gripper 9 and the second gripper 10 can be driven to approach each other to clamp and hold the temperature measuring connector protective plug 1 between the guide hole and the trigger rod 6. The first gripper 9 and the second gripper 10 realize the clamping and releasing action of the temperature measuring connector protective plug 1.

[0048] In this embodiment, the gripper mechanism can be two sets of parallel cylinders that drive the first gripper 9 and the second gripper 10 to perform clamping and releasing actions, or other drive mechanisms can drive the two mechanical gripper mechanisms to cooperate in achieving clamping and releasing actions.

[0049] The aforementioned guide block 4 is positioned in front of the substrate 3. The clamping mechanism is positioned at a distance from the guide block 4. The trigger rod 6 and spring 7 are positioned behind the substrate 3, corresponding to the guide hole. The limit switch 8 is positioned behind the trigger rod 6. The first gripper 9 and the second gripper 10 are symmetrically positioned on both sides of the substrate 3, one on the left and one on the right, and are located behind the guide block 4.

[0050] In this application, the end of the first clamping claw 9 facing the second clamping claw 10 is provided with an arc-shaped groove, and the end of the second clamping claw 10 facing the first clamping claw 9 is provided with an arc-shaped groove. The two arc-shaped grooves are respectively adapted and snapped into the side wall of the temperature measuring connector protective plug 1. The groove wall of the arc-shaped groove is provided with an anti-slip pad or anti-slip texture. The arc-shaped groove and the anti-slip pad or anti-slip texture can ensure the stability and reliability of the protective plug clamping and avoid slippage leading to disassembly and assembly failure.

[0051] The temperature measuring connector in this application is fixed to the end of the measuring gun, on which a temperature measuring probe is installed and used to measure the temperature of molten steel. The aforementioned temperature measuring connector protective plug 1 is installed at the end of the temperature measuring connector 2, and has a conical structure that engages with the outer shell of the temperature measuring connector 2 to lock in place. A guide block 4 is installed on the base plate 3 and serves to guide the installation and removal of the temperature measuring connector protective plug 1. A gripper mechanism is installed on the base plate 3 for clamping and releasing the temperature measuring connector protective plug 1 during installation and removal. A limit switch 8 and a compression spring 7 are arranged opposite each other and installed on the base plate 3 for detecting when the temperature measuring connector protective plug 1 is in place during installation and removal.

[0052] The method for installing the temperature sensor connector protective plug 1 using this disassembly and assembly device is as follows:

[0053] First, the robot, carrying a measuring gun and installing a temperature probe, inserts it into molten steel to perform temperature measurement. After measurement, the robot removes the discarded temperature probe and carries the measuring gun to the disassembly / assembly device. It then inserts the gun into the central guide hole along the guide cone surface of guide block 4 for guidance and positioning. Next, when the cone surface of the temperature measuring connector protective plug 1 contacts the temperature measuring connector 2, the gripper mechanism releases the protective plug 1. The robot, carrying the measuring gun, continues to move forward along the central guide hole of the guide block, ensuring a tight fit between the cone surface of the protective plug 1 and the connector 2. This continues until the protective plug 1 contacts the spring 7, compressing the spring and triggering the trigger rod 6 to activate the limit switch 8, which detects the position. Upon receiving this signal, the robot's control system stops moving forward with the measuring gun. Finally, the robot, carrying the measuring gun with the protective plug 1 installed, returns along the original path, installs a sampling probe, and inserts it into the molten steel for sampling.

[0054] The method for disassembling the protective plug 1 of the temperature measuring connector using this disassembly and assembly device is as follows:

[0055] After sampling is completed and the discarded probe is removed, the robot carries the probe to the disassembly / removal device to disassemble the protective plug 1 of the temperature measuring connector. First, the robot inserts the probe along the middle guide hole of the guide block 4 until the protective plug 1 of the temperature measuring connector contacts the spring 7 and triggers the end signal of the limit switch 8, at which point the robot stops moving. Second, after the gripper mechanism clamps the protective plug, the robot carries the probe backward along the guide hole of the guide block 4 until the temperature measuring connector 2 of the probe is completely removed from the guide block 4, and the disassembly of the protective plug is completed.

[0056] As can be seen, after the robot carrying the temperature measuring gun removes the discarded temperature measuring probe, the robot, in conjunction with the measuring gun, moves to the disassembly and assembly device to install the protective plug. Then, the robot carries the measuring gun to install the sampling probe for sampling. After sampling, the sampling probe is removed, and the protective plug is then removed via the disassembly and assembly device. The disassembly and assembly device provided in this application can automatically install the protective plug onto the temperature measuring connector and automatically remove it from the connector, thus protecting the connector and allowing the same measuring gun to complete temperature measurement and sampling operations sequentially. This avoids the problem of unreliable temperature data due to contamination of the connector during sampling.

[0057] The positioning detection component in this application uses a limit switch 8 capable of positioning detection. Of course, this positioning detection component can also be replaced by a photoelectric switch or a distance sensor, as long as it can realize the positioning detection of the protective plug installation and removal.

[0058] This application solves the problem of inaccurate temperature measurement data after using a single temperature measuring gun for robotic temperature sampling by installing a protective plug at the end of the temperature measuring connector of the sampling gun. This is achieved by isolating the tar generated by the combustion of the sampling probe from the temperature measuring connector, thus preventing tar contamination of the temperature measuring connector. At the same time, this application enables the same gun to complete temperature sampling operations sequentially. Compared with the traditional method of using two guns for temperature sampling operations separately, this application can reduce the configuration cost of the robotic temperature measuring gun, reduce the space occupied by the temperature sampling robot, and provide more possibilities for the layout of temperature sampling workstations in narrow spaces.

[0059] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0060] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
