Among them, a crucible cover is usually arranged on the top of the crucible to seal the crucible so that the temperature inside the crucible can rise rapidly.

[0003] In actual use, after the crucible is loaded with anode materials, it is first necessary to align the crucible cover with the crucible and place it on the crucible, and then transfer the crucible into the graphitization furnace; when the crucible is taken out of the furnace, it is necessary to first uncover the crucible, and then discharge the anode materials in the crucible. At present, a device for uncovering and covering a crucible for graphitizing anode materials is usually used to perform the uncovering or covering work of the crucible. However, when the existing device for uncovering and covering a crucible for graphitizing anode materials covers the crucible, it is not convenient to align the crucible cover with the crucible.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts also belong to the scope of protection of the present application.

[0036] As Figures 1-5 shown:

[0037] The graphite crucible lid uncovering and placing device for negative electrode materials provided by an embodiment of the present application includes a frame 1. A crucible conveyor 4 for conveying the crucible 2 in the X-axis direction is installed at the lower part of the frame 1, and the crucible conveyor 4 can limit the crucible 2 in the Y-axis direction to prevent the crucible 2 from shifting in the Y-axis direction when moving in the X-axis direction.

[0038] Above the crucible conveyor 4, there is a clamping mechanism 5 that can move in the X-axis direction or the Z-axis direction for grasping the crucible lid 3.

[0039] A limit member 12 is provided at the lower right end of the clamping mechanism 5. After the limit member 12 contacts the outer wall of the crucible 2, the crucible lid 3 clamped by the clamping mechanism 5 is located directly above the crucible 2.

[0040] On the frame 1, there is a crucible lid conveyor 6 located directly above the crucible conveyor 4 for carrying the crucible lid 3 and conveying the crucible lid 3 in the X-axis direction.

[0041] Further, the crucible cover 3 is located directly above the crucible conveyor 4, that is, the central line of the crucible conveyor 4 in the X-axis direction and the central line of the clamping mechanism 5 in the X-axis direction are in the same vertical plane. The crucible cover conveyor 6 is located directly above the crucible conveyor 4, that is, the central line of the crucible cover conveyor 6 in the X-axis direction and the central line of the crucible conveyor 4 in the X-axis direction are in the same vertical plane. Therefore, the central line of the crucible conveyor 4 in the X-axis direction, the central line of the clamping mechanism 5 in the X-axis direction, and the central line of the crucible cover conveyor 6 in the X-axis direction are in the same vertical plane.

[0042] In this embodiment, the X-axis direction is the left-right direction of the frame 1, the Y-axis direction is the front-back direction of the frame 1, and the Z-axis direction is the up-down direction of the frame 1. The limiting member 12 is located on the right side of the clamping mechanism 5, and the limiting member 12 contacts the middle position of the outer wall of the right end of the crucible 2. The crucible cover conveyor 6 is located directly above the right section of the crucible conveyor 4.

[0043] During use, the process of covering the crucible 2 and uncovering the crucible 2 is opposite, so only the process of covering the crucible 2 will be described. When covering the crucible 2, first place the crucible 2 on the crucible conveyor 4. Since the crucible conveyor 4 can limit the crucible 2 in the Y-axis direction, the crucible conveyor 4 drives the crucible 2 to move only in the X-axis direction. When the crucible 2 moves to the left side of the crucible cover conveyor 6, the crucible 2 stops moving. Then the clamping mechanism 5 moves above the crucible cover conveyor 6 and then moves down to the position of the crucible cover 3 to clamp the crucible cover 3. After the clamping mechanism 5 clamps the crucible cover 3, the clamping mechanism 5 moves up a certain distance and then moves to the left. When the limiting member 12 is located between the crucible 2 and the crucible cover conveyor 6, move the clamping mechanism 5 down and then move the clamping mechanism 5 to the left. When the limiting member 12 contacts the outer wall of the right end of the crucible 2, stop the movement of the clamping mechanism 5. At this time, the crucible cover 3 is concentric with the crucible 2. Finally, move the clamping mechanism 5 down to accurately place the crucible cover 3 on the crucible 2 and let the clamping mechanism 5 release the crucible cover 3.

[0044] The graphite crucible lid lifting and placing device for the negative electrode material provided in this embodiment is equipped with a crucible conveyor 4 on the supply rack 1 for transporting the crucible 2 in the X-axis direction, and the crucible conveyor 4 can limit the position of the crucible 2 in the Y-axis direction. Above the crucible conveyor 4, there is a clamping mechanism 5 that can move in the X-axis direction or the Z-axis direction for grasping the crucible lid 3. At the lower right end of the clamping mechanism 5, there is a limiting member 12. After the limiting member 12 contacts the outer wall of the crucible 2, the crucible lid 3 clamped by the clamping mechanism 5 is located directly above the crucible 2. On the rack 1, there is a crucible lid conveyor 6 located directly above the crucible conveyor 4. When placing the lid, it only needs to adjust the position of the crucible lid 3 in the X-axis direction and the Z-axis direction according to the limiting member 12, and then the crucible lid 3 can be moved directly above the crucible 2 to make the crucible lid 3 concentric with the crucible 2, thus facilitating the alignment of the crucible lid 3 with the crucible 2 and solving the problem that it is not easy to align the crucible lid 3 with the crucible 2 when placing the lid in the existing graphite crucible lid lifting and placing device for the negative electrode material.

[0045] In some embodiments of the present application, the crucible conveyor 4 includes a roller conveyor 401. The roller conveyor 401 is distributed along the X-axis direction and is fixed to the lower part of the rack 1.

[0046] At the upper end of the roller conveyor 401, two symmetrically distributed and X-axis direction distributed limiting plates 402 are fixed, and the distance between the two limiting plates 402 is equal to the outer diameter of the crucible 2, so that the crucible 2 will not shift in the Y-axis direction when moving along the X-axis, ensuring that the midline of the crucible 2 along the X-axis is always in the same vertical plane as the midline of the clamping mechanism 5 along the X-axis and the midline of the crucible lid conveyor 6 along the X-axis.

[0047] In this embodiment, the roller conveyor 401 is a prior art and will not be described in detail.

[0048] In some embodiments of the present application, a moving seat 7 and a rotatable lead screw 8 are provided at the top of the rack 1. Specifically, both ends of the lead screw 8 are rotatably connected to the rack 1 through bearings. The number of lead screws 8 is two and they are distributed along the X-axis direction. The two lead screws 8 are connected by a chain drive mechanism 9. The two lead screws 8 simultaneously pass through the moving seat 7 and are threadedly connected to the moving seat 7. One of the lead screws 8 is connected to a motor 10 that can drive it to rotate, and the motor 10 is fixed to the rack 1.

[0049] A first cylinder 11 distributed along the Z-axis direction is fixed to the moving seat 7, and the first cylinder 11 is connected to the clamping mechanism 5.

[0050] During use, the motor 10 drives the lead screw 8 connected thereto to rotate. The lead screw 8 drives another lead screw 8 to rotate synchronously through the chain drive mechanism 9, that is, the two lead screws 8 rotate synchronously. After the two lead screws 8 rotate synchronously, they drive the moving seat 7 to move in the X-axis direction. The moving seat 7 drives the clamping mechanism 5 to move in the X-axis direction through the first cylinder 11; when the first cylinder 11 extends, the clamping mechanism 5 moves downward, and when the first cylinder 11 contracts, the clamping mechanism 5 moves upward, so as to realize the movement of the clamping mechanism 5 in the X-axis direction and the Y-axis direction.

[0051] In some embodiments of the present application, the clamping mechanism 5 includes a mounting seat 501, and two clamping members 502 capable of moving toward or away from each other in the X-axis direction are provided on the mounting seat 501.

[0052] The mounting seat 501 is fixedly connected to the free end of the first cylinder 11, and the limiting member 12 is fixed to the lower end of the clamping member 502 close to the crucible lid conveyor 6. Specifically, the limiting member 12 is fixed to the lower end of the clamping member 502 on the right side.

[0053] In this embodiment, the midline of the clamping member 502 in the X-axis direction is the midline of the clamping mechanism 5 in the X-axis direction.

[0054] During use, the two clamping members 502 move toward each other to clamp the crucible lid 3, and the two clamping members 502 move away from each other to release the crucible lid 3.

[0055] In order to improve the stability of the clamping member 502 clamping the crucible lid 3. In some embodiments of the present application, the clamping member 502 is provided with an arc-shaped clamping surface for clamping the crucible lid 3 and adapted to the crucible lid 3, and a rubber pad 503 adapted thereto is fixed on the arc-shaped clamping surface.

[0056] In some embodiments of the present application, two slide bars 504 distributed symmetrically in the X-axis direction are fixed on the mounting seat 501, and the two slide bars 504 simultaneously penetrate through the two clamping members 502 and are slidably connected to the clamping members 502.

[0057] The two clamping members 502 are respectively connected to second cylinders 505, and the second cylinders 505 are fixed on the mounting seat 501. Specifically, the two second cylinders 505 are symmetrically distributed.

[0058] After the two second cylinders 505 act simultaneously, they can drive the two clamping members 502 to move toward or away from each other.

[0059] During use, when the two second cylinders 505 extend simultaneously, the two clamping members 502 move away from each other to release the crucible lid 3; when the two second cylinders 505 contract simultaneously, the two clamping members 502 move toward each other to clamp the crucible lid 3.

[0060] In some embodiments of the present application, a direct-acting travel switch 13 distributed along the X-axis direction is fixed on the limiting member 12, and the direct-acting travel switch 13 is connected to the motor 10.

[0061] Wherein, when the limiting member 12 contacts the outer wall of the right end of the crucible 2, the outer wall of the right end of the crucible 2 touches the direct-acting travel switch 13 to act, so that the motor 10 is in a power-off state. Then, after the crucible cover 3 is located directly above the crucible 2, the movement of the crucible cover 3 in the X-axis direction can be automatically stopped.

[0062] In some embodiments of the present application, the crucible cover conveyor 6 includes two side plates 601 distributed symmetrically along the X-axis direction. The side plates 601 are fixed on the frame 1. Between the two side plates 601, there are two belt conveying mechanisms 602 distributed along the X-axis direction and moving synchronously. The two belt conveying mechanisms 602 are symmetrically distributed, and there is a gap 603 between the two belt conveying mechanisms 602. When the clamping mechanism 5 clamps the crucible cover 3 on the crucible conveyor 4, the limiting member 12 can move into the gap 603, so that the limiting member 12 does not affect the clamping mechanism 5 to clamp the crucible cover 3 on the crucible conveyor 4.

[0063] In this embodiment, the belt conveying mechanism 602 is a prior art and will not be described in detail. The midline along the X-axis direction between the two belt conveying mechanisms 602 is the midline of the crucible cover conveyor 6 along the X-axis direction.

[0064] In some embodiments of the present application, those skilled in the art can design a corresponding automatic control system according to the common knowledge in the art to realize the automatic operation of uncovering and covering the crucible.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
