Abstract
Description
Technical Field
[0001] This application relates to the field of collection devices, and in particular to a cobalt powder collection device. Background Technology
[0002] In the production process, cobalt powder is often stored in saggers and transported through various processing stages via these saggers.
[0003] Currently, during the cobalt powder collection stage, the powder is often poured out of the crucible and collected in a container. Because cobalt powder is a lightweight, fine powder, this pouring process easily generates dust and pollutes the workshop environment. Therefore, the pouring operation is usually carried out mechanically in an enclosed space. The proposed solution uses a through-beam photoelectric sensor to detect when the crucible enters the operating area, then seals off the area before finally performing the pouring operation.
[0004] However, since cobalt powder will also generate dust during transportation, as the usage time increases, the cobalt powder passing through the photoelectric sensor will adhere to the transmitting end of the photoelectric sensor and accumulate to form a film that is difficult to remove. This will cause the light transmittance of the photoelectric sensor to decrease or even fail, thus affecting the normal operation of cobalt powder collection. Utility Model Content
[0005] In view of the shortcomings of the aforementioned related technologies, this application provides a cobalt powder collection device. By designing a detection component that detects the position of the crucible through contact with the crucible, the impact of cobalt powder adhesion on sensor accuracy is reduced, and the efficiency of cobalt powder collection is improved.
[0006] The cobalt powder collection device provided in this application adopts the following technical solution:

[0008] The workbench has a collection trough on its surface;

[0013] A flipping assembly, located on the workbench and inside the dust cover, is used to clamp the sagger and control the sagger opening to flip towards the collection trough.
[0014] Optionally, the detection assembly includes a torque sensor fixed on the workbench, a contact head rotatably disposed at the working end of the torque sensor, an elastic element for driving the contact head to reset, and a contact sensor disposed inside the dust cover. The contact head movably abuts against the crucible, and when the crucible is located inside the dust cover, the working end of the contact sensor abuts against the crucible.
[0015] Optionally, the contact head includes an extension rod rotatably disposed at the working end of the torque sensor and a contact wheel rotatably disposed at the end of the extension rod away from the torque sensor.
[0016] Optionally, the elastic element includes a torsion spring, one end of which is fixed to the extension rod and the other end of which is fixed to the outer wall of the torque sensor.
[0017] Optionally, the flipping assembly includes a baffle rotatably disposed on the worktable, two clamping plates respectively disposed at both ends of the baffle, a linear drive for driving one of the clamping plates to move toward or away from the other clamping plate, and a rotation drive for driving the baffle to rotate, wherein the contact sensor is fixed on the baffle.

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0033] This application discloses a cobalt powder collection device. (Refer to...) Figure 1 and Figure 2A cobalt powder collecting device includes a workbench 1, whose length is aligned with the conveying direction of a crucible. A conveying trough 2 is formed at one end of the top surface of the workbench 1 along its length. A conveying assembly is disposed in the conveying trough 2, comprising multiple conveying rollers 3 rotatably mounted within the conveying trough 2. The multiple conveying rollers 3 are spaced apart along the length of the workbench 1. The crucible is placed on the conveying rollers 3, and the workbench 1 controls the rotation of the conveying rollers 3 to convey the crucible. A dust cover 4 is installed downstream of the conveying rollers 3 on the workbench 1. An inlet 5 is formed on the side of the dust cover 4 facing the conveying rollers 3, and a closing door 6 is raised and lowered at the inlet 5. Specifically, the closing door 6 is driven to rise and fall by a motor (not shown in the figure) located on the inner wall of the dust cover 4. (See reference...) Figure 3 A collection trough 14 is provided on the workbench 1 below the dust cover 4. A flipping assembly 9 is provided on the workbench 1 between the conveying trough 2 and the collection trough 14 to clamp the crucible and control the opening of the crucible to flip towards the collection trough 14. The flipping assembly 9 is located inside the dust cover 4. In order to detect the position of the crucible by contacting the crucible and control the opening and closing of the sealing door 6, a detection assembly is also provided on the workbench 1.
[0034] Reference Figure 2 and Figure 3 The detection assembly includes a torque sensor 7 fixed on the workbench 1, a contact head 8 rotatably disposed at the working end of the torque sensor 7, an elastic element 11 for resetting the contact head 8, and a contact sensor disposed within the dust cover 4. When the contact head 8 is in contact with the crucible, and when the crucible is located within the dust cover 4, the working end of the contact sensor is in contact with the crucible. Specifically, refer to... Figure 2 The contact head 8 includes an extension rod 82 rotatably mounted at the working end of the torque sensor 7 and a contact wheel 81 rotatably mounted at the end of the extension rod 82 away from the torque sensor 7. A rotating column 10 is fixed on the side of the extension rod 82 near the contact sensor. The rotating column 10 is coaxially fixed with the working end of the contact sensor and its axis is perpendicular to the extension rod 82. The contact wheel 81 is fixed at the end of the extension rod 82 away from the rotating column 10. Furthermore, to repeatedly detect the position of multiple crucibles, the extended rod 82 needs to be reset after rotation. Specifically, the elastic element 11 includes a torsion spring, one end of which is fixed to the extension rod 82 and the other end to the outer wall of the torque sensor 7.
[0035] As the crucible is conveyed on the conveyor roller 3, the end of the crucible closest to the dust cover 4 first comes into contact with the contact wheel 81. At this time, the continued movement of the crucible drives the contact wheel 81, the extension rod 82, and the rotating column 10 to rotate. The rotation of the rotating column 10 triggers the torque sensor 7 to work, transmitting a signal to the external control system to drive the sealing door 6 to rise. As the crucible moves, the contact wheel 81 rotates on the extension rod 82, thereby reducing the friction between the contact wheel 81 and the surface of the crucible and minimizing changes to the crucible's movement trajectory. As the crucible continues to move, when the contact wheel 81 separates from the crucible, the torsion spring drives the extension plate to rotate and reset, thus facilitating the detection of the position of the next passing crucible and controlling the opening of the sealing door 6.
[0036] In other embodiments, the contact wheel 81 can also be fixed to the ball at the end of the extension rod 82, which can reduce the frictional force on the crucible.
[0037] After the sagger moves to the point of disengagement from the contact wheel 81, it enters the dust hood 4 through the feed inlet 5, closing the sealing door 6 and flipping the sagger. (Refer to...) Figure 3 A rotating shaft 13 is mounted on the workbench 1 at the edge of the collection tank 14, and the rotation axis of the rotating shaft 13 is arranged along the width direction of the workbench 1. The flipping assembly 9 includes a baffle 91 fixedly sleeved on the rotating shaft 13, two clamping plates 92 respectively provided at both ends of the baffle 91, a linear drive 93 for driving one of the clamping plates 92 to move closer to or away from the other clamping plate 92, and a rotation drive 94 for driving the rotating shaft 13 to rotate. A contact sensor is fixed on the plate surface of the baffle 91 facing the crucible. Specifically, mounting plates 12 are fixed at both ends of the baffle 91. Two linear drive 93s are provided, and the two linear drive 93s are respectively fixed on the two mounting plates 12. The two clamping plates 92 are located between the two mounting plates 12, and the working end of the linear drive 93 passes through the mounting plate 12 and connects to the corresponding clamping plate 92. The linear drive component 93 can be a hydraulic cylinder, an electric push rod, etc. In this embodiment, it is preferably a hydraulic cylinder. The cylinder body of the hydraulic cylinder is fixed on the mounting plate 12, and the hydraulic rod is fixed on the mounting plate 12 and the clamping plate 92. The rotation drive component 94 can be a rotary motor or a servo motor. In this embodiment, it is preferably a servo motor. The servo motor is fixed on the worktable 1, and its working end is coaxially fixed with the rotating shaft 13.
[0038] When the crucible is conveyed between the two clamping plates 92 until it comes into contact with the working end of the contact sensor on the baffle 91, the contact sensor sends a signal to the external control system, thereby driving the closing door 6 to descend. At the same time, the signal controls the hydraulic cylinder to start, driving the two clamping plates 92 to move closer to each other until the crucible is clamped. Finally, the servo motor is controlled to drive the rotating shaft 13 to rotate, causing the baffle 91 and the crucible to rotate toward the collection tank 14. When the rotation angle reaches 170 degrees, the rotation stops and the crucible is reversed to reset, completing the process of collecting cobalt powder in the crucible.
[0039] Furthermore, refer to Figure 3 To minimize the risk of the sagger getting stuck when it moves to the clamping plate 92, the ends of the two clamping plates 92 that are close to each other and away from the baffle 91 are rounded, thereby guiding the sagger between the two clamping plates 92.
[0040] The implementation principle of the cobalt powder collection device in this application embodiment is as follows: The conveying roller 3 is started by the workbench 1, and the crucible is conveyed on the conveying roller 3. The end of the crucible near the dust cover 4 first abuts against the contact wheel 81. At this time, the continued movement of the crucible drives the contact wheel 81, the extension rod 82, and the rotating column 10 to rotate. The rotation of the rotating column 10 triggers the torque sensor 7 to work, transmitting a signal to the external control system to drive the closed door 6 to rise. As the crucible moves, the contact wheel 81 rotates on the extension rod 82, thereby reducing the friction between the contact wheel 81 and the surface of the crucible and minimizing changes to the movement trajectory of the crucible. As the crucible continues to move, when the contact wheel 81 separates from the crucible, the torsion spring drives the extension plate to rotate and reset, thus facilitating the detection of the position of the next passing crucible and controlling the opening of the closed door 6. After the crucible moves away from the contact wheel 81, it enters the dust cover 4 through the feed inlet 5. When the crucible is conveyed between the two clamping plates 92 until it comes into contact with the working end of the contact sensor on the baffle 91, the contact sensor sends a signal to the external control system, thereby driving the closing door 6 to descend. At the same time, the signal controls the hydraulic cylinder to start, driving the two clamping plates 92 to move towards each other until the crucible is clamped. Finally, the servo motor is controlled to drive the rotating shaft 13 to rotate, driving the baffle 91 and the crucible to rotate towards the collection tank 14. When the rotation angle reaches 170 degrees, the rotation stops and the crucible is reversed to reset, completing the process of collecting cobalt powder in the crucible.
