[0002] The main purpose of inspecting molten steel samples in iron and steel smelting is for quality control and analysis. Since the molten steel may undergo changes in temperature, composition, and structure during the smelting process, sample inspection can help monitor these changes, timely adjust the smelting parameters, and ensure the quality of the final product.

[0003] In the traditional iron and steel metallurgy industry, manual labor is relied on to send the molten steel samples after sampling to the inspection room. After sampling, the samples are usually sealed in suitable containers or packages to prevent contamination or damage to the samples, and then the sealed samples are transported to a dedicated inspection room.

[0004] The molten steel sample is in a super-high temperature solid state of a glowing body (about 1000 °C). There are relatively large potential safety hazards for manual labor during the operation process, which have an impact on the safety and health of personnel. Moreover, the time taken for manual sample feeding is uncontrollable, which easily leads to a delay in the sample inspection and analysis results, and has a greater impact on the control of the existing casting composition. Furthermore, with the development of industrial automation, this sample feeding method is inefficient and has a high labor cost. Therefore, it is necessary to propose a new technical solution to solve the problems existing in the prior art. Summary of the Utility Model

Applying this application in production practice can achieve unmanned operation, promote safe production, and achieve staff reduction and efficiency increase. The structure and usage process of the molten steel sample feeding device will be described in detail below.

[0033] This application provides a molten steel sample feeding device, which mainly includes a sample loading part, a conveying part, and a sample feeding part. Among them: The conveying part includes a conveying line 3. On the conveying line 3, a sample box transfer station D, a sample box opening / closing station C, and a sample receiving waiting station B are sequentially arranged. The conveying line 3 can reciprocally transport the sample box placed on it between the sample box transfer station D, the sample box opening / closing station C, and the sample receiving waiting station B to realize the automatic conveying of the sample box, as Figures 1 to 3 .

[0034] In this embodiment, a sample feeding part and a sample box transfer component 6 are arranged beside the sample box transfer station D. A sample feeding port A is provided at a position where the sample feeding part is close to the conveying line 3. The sample feeding part can realize the transfer of an empty sample box and a sample box filled with a sample between the sample feeding port A and the inspection room. The sample box transfer component 6 realizes the transfer of an empty sample box and a sample box filled with a sample between the sample feeding port A and the sample box transfer station D.

[0036] In this embodiment, a sample loading part is arranged beside the sample receiving waiting station B. The sample loading part is used to load the qualified molten steel sample with a cut handle into the open sample box located at the sample receiving waiting station B.

[0037] Therefore, in this application, sample loading is automatically performed by the sample loading part. The empty sample box sent from the inspection room is sent to the conveying part by the sample sending part, and the sample box containing the sample is sent back to the inspection room. The conveying part realizes the sample transfer between the sample loading part and the sample sending part.

[0038] In one embodiment, the conveying line 3 can be a flexible chain plate conveying line, a belt conveying line or a roller conveying line, and mainly serves to convey the sample box. When the conveying line 3 is a flexible chain plate conveying line, a fixed sample box storage station can be equipped on the flexible chain plate conveying line. The flexible characteristics of the chain plate line can be applied to various complex sites, which is beneficial to the conveying construction and long-distance conveying.

[0039] In one embodiment, the sample sending part includes a pneumatic sample sender and / or an electric push-pull sample sender, as long as the conveying requirement is met. If a pneumatic sample sender is adopted, one end of the conveying pipe of the sender is connected to the sample box receiving and sending port of the inspection room, and the other end is connected to the sample sending port A.

Preferably, an electromagnet can be equipped for the gripper, and the gripper + electromagnet adsorption is used for grasping and fixing, which can ensure smooth placement when loading into the pneumatic sample sending inlet.

The lifting component can drive the fixture to perform lifting motion. The lifting component is a structure such as a lifting rod. The rotary table can drive the lifting component to rotate relative to the conveying line 3 and / or other devices around the conveying line 3 to take the picked-up upper cover away from the conveying line 3 to the waiting position.

[0042] In one embodiment, the sample loading part mainly includes a molten steel sample shearing handle component 2 and a vision-guided sampling component 1. Among them: the molten steel sample shearing handle component 2 is used to perform shearing handle treatment on the molten steel sample placed at the shearing handle station for subsequent automatic sampling operations; the vision-guided sampling component 1 is mainly used to control the position state of the molten steel to make it reach the preset standard state and then take out the molten steel in the standard state for the next operation.

[0043] In one embodiment, the vision-guided sampling component 1 mainly includes a picking component and a sampling vision CCD component 13. The sampling vision CCD component 13 adopts conventional industrial vision CCD technology. The sampling vision CCD component 13 includes an image acquisition module (camera), an image processing module, and an image analysis module. The image analysis module outputs signals representing the coordinate of the feature points of the positional relationship of the object and other relevant information, and sends the signals to the controller of the vision-guided sampling component 1 and controls the action of the picking component through the controller.

[0044] In one embodiment, referring to Figure 1 , the structure of the vision-guided sampling component 1 is as follows: The vision-guided sampling component 1 mainly includes a sampling module Z-axis component 11, a sampling module Y-axis component 14, a sampling module X-axis component 15, and a sampling module R-axis component 12. Among them, the sampling module Z-axis component 11, the sampling module Y-axis component 14, and the sampling module X-axis component 15 form a three-dimensional coordinate system structure. The sampling module R-axis component 12 is installed on the sampling module Z-axis component 11. In this application, the sampling module Z-axis component 11, the sampling module Y-axis component 14, and the sampling module X-axis component 15 are all sliding guiding components. Such a structural design is to achieve arbitrary adjustment of the sampling vision CCD component 13 and the picking component installed on the sampling module R-axis component 12.

[0045] Specifically, the sampling module Z-axis component 11 is a vertically arranged long strip-shaped structural member. A slideway allowing the sampling module R-axis component 12 to reciprocate up and down is provided on the sampling module Z-axis component 11. The sampling module R-axis component 12 realizes movement and in-place stopping on the sampling module Z-axis component 11 through a slider and a limiting member, etc.

[0046] The sampling module Y-axis component 14 is a horizontally arranged long strip-shaped structural member. A slideway allowing the sampling module Z-axis component 11 to reciprocate left and right is provided on the sampling module Y-axis component 14. The sampling module Z-axis component 11 realizes movement and in-place stopping on the sampling module Y-axis component 14 through a slider and a limiting member, etc.

[0047] The sampling module X-axis component 15 is a horizontally arranged long strip-shaped structural member. The length direction of the sampling module X-axis component 15 is perpendicular to the length direction of the sampling module Y-axis component 14. A slideway allowing the sampling module Y-axis component 14 to reciprocate back and forth is provided on the sampling module X-axis component 15. The sampling module Y-axis component 14 realizes movement and in-place stopping on the sampling module X-axis component 15 through a slider and a limiting member, etc.

[0048] The aforementioned picking component may include a vertically arranged connecting rod and a vacuum suction head, and sample picking can be performed through vacuum suction. The aforementioned sampling vision CCD component 13 includes a camera and an image processing module. It collects image information of the molten steel sample by taking pictures, obtains the position and state information of the molten steel sample, and then the vision-guided sampling component 1 adjusts the position of the picking component, thereby adjusting the position and state of the molten steel sample through the picking component. After adjusting to the target state, sample picking is performed through the picking component. In order to collect weight information while picking samples, a weighing sensor for weighing the picked molten steel sample may also be provided on the R-axis component 12 of the sampling module.

[0049] In another embodiment, the vision-guided sampling component 1 in the present application may directly adopt an industrial robot, such as a six-axis robot. The sampling vision CCD component 13 and the picking component may be installed at the execution end of the six-axis robot. The sampling vision CCD component 13 collects image information of the molten steel sample by taking pictures, obtains the position and state information of the molten steel sample, and after obtaining the information, it can send it to the control system of the six-axis robot. Then, the six-axis robot drives the picking component to position and pick up the molten steel sample, and the picking component may be a fixture installed at the execution end of the six-axis robot, such as a jaw and other structures, or a vacuum suction head may also be used, as long as it can achieve sample picking. Similarly, a weighing sensor for weighing the picked molten steel sample may also be provided on the fixture to obtain the weight information of the sample while picking samples.

[0050] In one embodiment, an artificial sampling station and a defective product recycling station may be provided beside the sample receiving waiting station B. For example, after the vision-guided sampling component 1 confirms that the shear handle is qualified, the molten steel sample with a qualified shear handle can be placed at the artificial sampling station. Cooling water may be provided at the artificial sampling station. After the molten steel sample is cooled by the cooling water, it is manually picked up and placed into the sample feeding port A of the pneumatic sample feeder. After the vision-guided sampling component 1 confirms that the shear handle is unqualified, the molten steel sample with an unqualified shear handle can be placed at the defective product recycling station.

[0051] In one embodiment, a first detection part for detecting the sample box is provided at the sample feeding port A; a second detection part for detecting the sample box is provided at the sample box transfer station D; a third detection part for detecting the sample box is provided at the sample box switch station C; a fourth detection part is provided at the sample receiving waiting station B; the setting of each detection part is mainly to achieve the in-place detection of the sample box and the signal transmission to each execution mechanism connected thereto, so as to realize a closed-loop overall automated control system.

[0052] Specifically, the first detection unit is connected to the sample box transfer component 6 by signal, and the first detection unit is also connected to the drive assembly of the sample feeding unit by signal; the second detection unit is connected to the drive motor of the conveyor line 3 by signal, and the second detection unit is also connected to the sample box transfer component 6 by signal; the third detection unit is connected to the sample box lid opening / closing component 5 by signal, and the fourth detection unit is connected to the drive motor of the conveyor line 3 and the sample loading unit by signal respectively.

[0053] When the sample feeding unit transports an empty sample box to the sample feeding port A, the first detection unit detects the empty sample box and sends a signal to the sample box transfer component 6. The sample box transfer component 6 receives the signal and transfers the empty sample box at the sample feeding port A to the sample box transfer station D of the conveyor line 3.

[0054] After the empty sample box is transferred to the sample box transfer station D, the second detection unit detects the empty sample box and sends a signal to the drive motor. The drive motor receives the signal and transports the empty sample box to the sample box lid opening / closing station C.

[0055] After the empty sample box is transferred to the sample box lid opening / closing station C, the third detection unit detects the empty sample box and sends a signal to the sample box lid opening / closing component 5. After receiving the signal, the sample box lid opening / closing component 5 picks up the upper lid of the empty sample box and moves the upper lid to the waiting position away from the conveyor line 3.

[0056] The sample box lid opening / closing component 5 is connected to the drive motor of the conveyor line 3 by signal. After moving the upper lid to the waiting position, the sample box lid opening / closing component 5 sends a signal to the drive motor, and the conveyor line 3 transports the empty sample box in the open state to the sample receiving waiting station B.

[0057] After the empty sample box is transferred to the sample receiving waiting station B, the fourth detection unit is used to detect the empty sample box and send a signal to the sample loading unit. After the sample loading unit receives the signal and loads the qualified steel melt sample with cut handle into the empty sample box, the fourth detection unit is used to send a signal to the drive motor, and the sample box containing the steel melt sample is sent to the sample box lid opening / closing station C.

[0058] After the third detection unit detects the sample box containing the steel melt sample, it sends a signal to the sample box lid opening / closing component 5. The sample box lid opening / closing component 5 transfers the upper lid from the waiting position to above the sample box and correspondingly buckles the upper lid on the sample box; after the sample box lid opening / closing component 5 completes the upper lid buckling action, it sends a signal to the drive motor, and the conveyor line 3 transports the sample box containing the encapsulated steel melt sample to the sample box transfer station D.

[0059] After the second detection unit detects the sample box containing the encapsulated steel melt sample, it sends a signal to the sample box transfer component 6. The sample box transfer component 6 is used to transfer the sample box containing the encapsulated steel melt sample to the sample feeding port A; after the first detection unit detects the sample box containing the encapsulated steel melt sample, it sends a signal to the drive assembly of the sample feeding unit, and the sample feeding unit is used to transfer the sample box containing the encapsulated steel melt sample to the inspection room.

[0060] In this application, each of the above-mentioned detection parts may include a plurality of sensors or detection devices such as travel switches, and it is only necessary to be able to realize the in-place detection of the sample box and the transmission of the in-place signal.

[0061] The sample delivery process of the molten steel sample delivery device provided by this application is as follows:

[0062] After the vision-guided sampling component 1 picks up the sample and adjusts the position state of the sample, the sample is placed at the shearing handle station of the sample shearing handle component 2, and the sample shearing handle operation is completed by the sample shearing handle component 2; at the same time, the empty sample box is transported from the inspection and analysis laboratory to the sample delivery port A through the pneumatic sample delivery machine, the sample box transfer component 6 is started, the returned empty sample box is picked up and placed at the sample box transfer station D, the sample box transfer component 6 is reset and the conveyor line 3 is started to move the empty sample box to the sample box switch station C, the sample box switch component is started to remove the upper cover of the sample box and keep it in the removed state, and the lifting component of the sample box switch component moves out of the range of the conveyor line 3 and waits to be pressed in after the sampling is completed; at the same time, the conveyor line 3 is started to move the empty sample box after opening the cover to the sample receiving waiting station B, waiting for the shearing handle to be completed, and verifying the state after the sample shearing handle is completed. After passing the verification, the opened empty sample box is put in; when the shearing handle is completed, the sampling vision CCD component 13 on the vision-guided sampling component 1 moves to the shearing handle station to identify and judge the state of the sample after the shearing handle. If the shearing handle is judged to be successful, the sample after the shearing handle is picked up and transported to the sample receiving waiting station B or the manual sampling position; if manual sample delivery is required, the sample after the shearing handle is put into the manual sampling position, and after being cooled by the cooling water at the manual sampling position, it is picked up manually and put into the sample delivery port A; if automatic sample delivery is required, the sample after the shearing handle is put into the opened empty sample box at the sample receiving waiting station B; the conveyor line 3 is started to transport it to the sample box switch station C, and then the sample box switch component is started to press the upper cover of the sample box into the sample box, and the sample box switch component is reset; the conveyor line 3 is started to transport the sample box after the capping is completed to the sample box transfer station D, the sample box transfer component 6 is started, the sample box is placed at the sample delivery port A, and the sample box is transported to the inspection and analysis laboratory by the pneumatic sample delivery machine, and the sample delivery work process is completed.

[0063] Therefore, in practical applications, after sampling is completed, automatic sample delivery can be carried out through this device. This device decomposes the sample delivery process, solidifies the operation process, ensures the continuity of the operation, realizes the unmanned operation route, effectively connects the automation operation process control between automatic sampling and automatic inspection and analysis, fills the industry gap, shortens the operation time of the intermediate link from sampling to inspection of the sample, and improves the quality control ability during the casting process.
