Description

Crucible transfer device for graphitization furnace

[0001] The present embodiments relate to a crucible conveying device for a graphitizing furnace for safely and efficiently conveying a crucible in the graphitizing furnace process of an artificial graphite plant.

[0002] Artificial graphite is essential for electric vehicle batteries, electrodes, and high-temperature mechanical parts.

[0003] The production of artificial graphite primarily takes place in a graphitization furnace, in which raw carbon is heated to a high temperature to form a graphite structure.

[0004] A graphitization furnace is equipment that induces graphitization by heating carbon raw materials to 2,500°C to 3,000°C, and is used to graphitize carbon-based raw materials to form a graphite structure.

[0005] The crucible helps the raw material form crystals with a graphite structure while maintaining a high temperature, and at the same time ensures that graphitization is carried out uniformly.

[0006] In the graphitization process, the high-temperature treatment process can only proceed normally if the crucible reaches a specific position accurately; if it does not reach the accurate position, an imbalance in heat distribution may occur, leading to incomplete conversion of the raw material.

[0007] Accordingly, in the graphitization process, a conveying device is required to safely bring in and take out crucibles in a high-temperature environment.

[0008] These embodiments can provide a crucible transfer device for a graphitization furnace that significantly improves stability and efficiency by enabling the crucible to be accurately grasped and moved in a high-temperature environment through the movement of a moving plate equipped with a gripper module moving closer to or further away from a base plate equipped with a gripper module.

[0009] In one aspect, the present embodiments may provide a crucible transfer device for a graphitization furnace, characterized by comprising: a base plate coupled to a connecting frame of a transfer module that moves along a transfer rail; one or more moving plates arranged at a certain distance from the base plate and moving in a direction closer to or further away from the base plate; a driving unit installed on either the base plate or the moving plate, to which one side of an operating rod that performs linear motion is insertedly coupled; a fixed bracket installed on the other of the base plate or the moving plate, to which the other side of the operating rod is coupled so that the moving plate moves closer to or further away from the base plate; and a gripper module each installed on either one or more of the base plate or the moving plate, wherein two or more clamping parts act with each other to grasp a cylindrical object.

[0010] According to the embodiments, a crucible transfer device for a graphitization furnace can be provided, which significantly improves stability and efficiency by enabling a cylindrical object to be accurately grasped and moved in a high-temperature environment as the moving plate on which the gripper module is installed moves closer to or further away from the base plate on which the gripper module is installed.

[0011] In addition, by rotating the grip portion around the vertical axis and the horizontal axis, it is possible to provide a crucible transfer device for a graphitization furnace that can precisely respond to the movement or deformation of a cylindrical object and maintain even distribution of load and accurate fixation.

An actuator (500) that provides rotational force to the first drive link (200a) and the second drive link (200b) so that the drive shaft (520) is coupled to the first drive link (200a) so that it can rotate in one direction or in the opposite direction around the horizontal first-third rotation axis (a3) ​​of the first drive link (200a) located above the first-first rotation axis (a1), and the cylinder (510) is coupled to the second drive link (200b) so that it can rotate in one direction or in the opposite direction around the horizontal second-third rotation axis (b3) of the second drive link (200b) located above the second-first rotation axis (b1), and so that the first-third rotation axis (a3) ​​and the second-third rotation axis (b3) move in a direction that moves closer or further apart; A first operating frame (400a) having one or more clamping parts (600) connected to the first driving link (200a) via the horizontal direction first-fourth rotation axis (a4) of the first driving link (200a), the upper side of which is located below the first-first rotation axis (a1); and a second operating frame (400b) having one or more clamping parts (600) connected to the lower side of the second driving link (200b), the upper side of which is located below the second-first rotation axis (b1), via the horizontal direction second-fourth rotation axis (b4) of the second driving link (200b), the upper side of which is located below the second-first rotation axis (b1);A first auxiliary link (300a) which is coupled to the support frame (100) so as to be rotatable in one direction or opposite direction around the horizontal first-second rotation axis (a2) of the support frame (100) located at the lower side of the first-first rotation axis (a1), and which is coupled to the first operating frame (400a) via the horizontal first-fifth rotation axis (a5) of the first operating frame (400a) located at the lower side of the first-fourth rotation axis (a4); and a second auxiliary link (300b) is symmetrically positioned with respect to the first auxiliary link (300a) with respect to the support frame (100), and is coupled to the support frame (100) so as to be rotatable in one direction or opposite direction around the horizontal second-second rotation axis (b2) of the support frame (100) which is located on the lower side of the second-first rotation axis (b1), and is coupled to the second operating frame (400b) via the horizontal second-fifth rotation axis (b5) of the second operating frame (400b) which is located on the lower side of the second-fourth rotation axis (b4);

[0053] In this embodiment, the support frame (100) is installed on the upper side of the base plate (50) or the movable plate (50a, 50b) to support the rotation of the first drive link (200a), the second drive link (200b), the first auxiliary link (300a) and the second auxiliary link (300b).

[0054] At this time, a first-1 rotation axis (a1) is installed on the upper side of one side of the support frame (100), a first-2 rotation axis (a2) is installed on the lower side of one side, a second-1 rotation axis (b1) is installed on the upper side of the other side, and a second-2 rotation axis (b2) is installed on the lower side of the other side.

[0055] The first drive link (200a) is coupled to the support frame (100) so as to be rotatable in one direction or opposite direction around the horizontal first rotation axis (a1) of the support frame (100).

[0056] At this time, a first-3 rotation shaft (a3) ​​is installed on the upper part of the first-1 rotation shaft (a1) in the first drive link (200a), and a first-4 rotation shaft (a4) is installed on the lower part of the first-1 rotation shaft (a1).

[0057] The first drive link (200a) rotates in one direction or opposite direction around the first rotation axis (a1) by the operation of the actuator (500), and moves the first operating frame (400a) in the direction where the cylindrical object (D) is located or opposite direction so that the first clamping part (600a) comes into contact with or separates from the cylindrical object (D).

[0058] The second drive link (200b) is coupled to the support frame (100) so as to be rotatable in one direction or opposite direction around the horizontal second-1 rotation axis (b1) of the support frame (100).

[0059] At this time, in the second drive link (200b), a second-third rotation shaft (b3) is installed on the upper part of the second-first rotation shaft (b1), and a second-fourth rotation shaft (b4) is installed on the lower part of the second-first rotation shaft (b1).

[0060] The second drive link (200b) rotates in one direction or opposite direction around the second-1 rotation axis (b1) by the operation of the actuator (500), and moves the second operating frame (400b) in the direction where the cylindrical object (D) is located or opposite direction so that the second clamping part (600b) comes into contact with or separates from the cylindrical object (D).

[0061] The actuator (500) includes a drive shaft (520) coupled to either the first drive link (200a) or the second drive link (200b), and a cylinder (510) coupled to the other of the first drive link (200a) or the second drive link (200b), and as the drive shaft (520) is inserted into the cylinder (510), rotational force is provided to the first drive link (200a) and the second drive link (200b).

[0062] At this time, one side of the drive shaft (520) of the actuator (500) is connected to the cylinder (510) so that its length can be extended.

[0063] For example, in this embodiment, the actuator (500) is coupled to the first drive link (200a) such that the drive shaft (520) is positioned above the first rotation axis (a1) and rotates in one direction or in the opposite direction around the horizontal first-third rotation axis (a3) ​​of the first drive link (200a), and the cylinder (510) is coupled to the second drive link (200b) such that the cylinder is positioned above the second rotation axis (b1) and rotates in one direction or in the opposite direction around the horizontal second-third rotation axis (b3) of the second drive link (200b), and is extended to move the first-third rotation axis (a3) ​​and the second-third rotation axis (b3) closer together or further apart, thereby providing rotational force to the first drive link (200a) and the second drive link (200b).

[0064] The first operating frame (400a) is coupled to the first driving link (200a) via the horizontal first-fourth rotation axis (a4) of the first driving link (200a), the upper side of which is located below the first-first rotation axis (a1), and one or more clamping parts (600) are coupled to the lower side.

[0065] The second operating frame (400b) is connected to the second driving link (200b) via the horizontal second-fourth rotation axis (b4) of the second driving link (200b), the upper side of which is located below the second-first rotation axis (b1), and one or more clamping parts (600) are connected to the lower side.

[0066] One side of the first auxiliary link (300a) is connected to the support frame (100) so as to be rotatable in one direction or opposite direction around the horizontal first-second rotation axis (a2) of the support frame (100), which is located below the first-first rotation axis (a1), and the other side is connected to the first operating frame (400a) via the horizontal first-fifth rotation axis (a5) of the first operating frame (400a), which is located below the first-fourth rotation axis (a4).

[0067] The first auxiliary link (300a) is rotatably coupled to the support frame (100) and supports the first operating frame (400a) which moves in the direction or opposite direction where the cylindrical object (D) is located by the first driving link (200a).

[0068] Accordingly, the first operating frame (400a) moves in the direction where the cylindrical object (D) is located or in the opposite direction without rotating due to the first driving link (200a) and the first auxiliary link (300a).

[0069] One side of the second auxiliary link (300b) is connected to the support frame (100) so as to be rotatable in one direction or opposite direction around the horizontal second-second rotation axis (b2) of the support frame (100), which is located below the second-first rotation axis (b1), and the other side is connected to the second operating frame (400b) via the horizontal second-fifth rotation axis (b5) of the second operating frame (400b), which is located below the second-fourth rotation axis (b4).

[0070] The second auxiliary link (300b) is rotatably coupled to the support frame (100) and supports the second operating frame (400b) which moves in the direction or opposite direction where the cylindrical object (D) is located by the second driving link (200b).

[0071] Accordingly, the second operating frame (400b) moves in the direction where the cylindrical object (D) is located or in the opposite direction without rotating due to the second driving link (200b) and the second auxiliary link (300b).

[0072] Specifically, when the actuator (500) operates to rotate the first drive link (200a) and the second drive link (200b), the clamping part (600) connected to the first operating frame (400a) and the second operating frame (400b) can grasp or release the cylindrical object (D), and the multiple clamping parts (600) interact to perform a stable grip operation of the cylindrical object (D).

[0073] In particular, the symmetrical arrangement of the first drive link (200a) and the second drive link (200b), the first auxiliary link (300a) and the second auxiliary link (300b), and the first operating frame (400a) and the second operating frame (400b) maintains balance and enables various movements according to the size and shape of the cylindrical object (D).

[0074] Here, the support frame (100) includes a link guide (110) that restricts the rotational movement of the first auxiliary link (300a) and the second auxiliary link (300b).

[0075] In this embodiment, the link guide (110) restricts the rotational movement of the first auxiliary link (300a) and the second auxiliary link (300b), increases the strength of the support frame (100), and prevents bending or deformation.

[0076] The gripper module (40) of the embodiment described above can be effectively applied in a graphitization process and can be modified in various ways as needed.

[0077] In particular, the driving method of the actuator (500) can be changed to a hydraulic, pneumatic, or electric type depending on the working conditions.

[0078] FIG. 6 is a drawing showing the operation in which the grip portion (700) contacts the cylindrical object (D) in a direction facing each other in conjunction with the extension operation of the actuator (500), and FIG. 7 is a drawing showing the operation in which the grip portion (700) separates from the cylindrical object (D) in a direction facing each other in conjunction with the contraction operation of the actuator (500).

[0079] In this way, the clamping part (600) contacts or separates from the cylindrical object (D) in a direction facing each other in conjunction with the extension and retraction movement of the actuator (500) and performs a gripping movement.

[0080] In this embodiment, the shape and position of the clamping part (600) may be changed according to the shape and characteristics of the cylindrical object.

[0081] Referring to FIG. 8, a clamping part (600) according to one embodiment comprises: a support bracket (610) coupled to the lower side of a first operating frame (400a) or a second operating frame (400b); a first fixing part (820) coupled to the support bracket (610) and having a first vertical support shaft part (822) formed on the lower side; a second fixing part (840) coupled to the support bracket (610) and having a second vertical support shaft part (842) formed on the upper side; and a first rotational support part (860) having a support groove (862) formed on the upper side and the lower side into which the first support shaft part (822) and the second support shaft part (842) are inserted, respectively, and rotating in one direction or opposite direction around the central axis of the first support shaft part (822) and the second support shaft part (842) between the first fixing part (820) and the second fixing part (840). and includes a grip portion (700) that is coupled to the first rotational support portion (860) and contacts or is spaced apart from the cylindrical object (D).

[0082] The support bracket (610) is coupled to the lower side of the first operating frame (400a) or the second operating frame (400b), such that a pair is coupled to the lower side of the first operating frame (400a) at a certain distance apart, and a pair is coupled to the lower side of the second operating frame (400b) at a certain distance apart.

[0083] At this time, one of the support brackets (610) of the pair of support brackets (610) coupled to the lower side of the first operating frame (400a) is positioned to face the other support bracket (610) of the pair of support brackets (610) coupled to the lower side of the second operating frame (400b), and the other support bracket (610) of the pair of support brackets (610) coupled to the lower side of the first operating frame (400a) is positioned to face the support bracket (610) of the pair of support brackets (610) coupled to the lower side of the second operating frame (400b).

[0084] The first fixed part (820) is connected to the support bracket (610) through a fastening member (C0), and a first vertical support shaft part (822) is formed on the lower side and is fitted into the upper support groove (862) of the first rotational support part (860).

[0086] The first rotational support member (860) has a support groove (862) formed on the upper and lower sides into which the first support shaft member (822) and the second support shaft member (842) are inserted, respectively, and rotates in one direction or opposite direction around the vertical central axis of the first support shaft member (822) and the second support shaft member (842) between the first fixing member (820) and the second fixing member (840).

[0087] The grip portion (700) is connected to the first rotational support portion (860) via a fastening member (C2), and rotates in one direction or opposite direction around the vertical central axis of the first support shaft portion (822) and the second support shaft portion (842), and contacts or separates from the cylindrical object (D).

[0088] That is, the grip portion (700) is structured to rotate left and right around the vertical central axis of the first support shaft portion (822) and the second support shaft portion (842) and to come into contact with or be separated from the cylindrical object (D), thereby enabling the pressure to be evenly distributed at various points depending on the size and shape of the cylindrical object (D).

[0089] At this time, the grip portion (700) includes a projection portion (710) formed protruding from the surface facing the cylindrical object (D) so as to prevent the accident of the cylindrical object (D) being damaged or falling due to slipping caused by poor contact.

[0090] The protrusion (710) is formed in a sawtooth shape that slopes upward from the surface of the grip portion (700) facing the cylindrical object (D) toward the cylindrical object (D) so that slip does not occur when gripping the cylindrical object (D).

[0091] Here, an insertion groove (620) into which a grip portion (700) is inserted is formed in the direction in which the cylindrical object (D) of the support bracket (610) is located, inclined surfaces (660) are formed on both sides of the insertion groove (620), and a receiving groove (640) in which a first fixing portion (820), a second fixing portion (840), and a first rotational support portion (860) are received is formed in the middle side of the insertion groove (620).

[0092] And, a guide member (680) is attached to the lower side of the support bracket (610) to guide the movement so that the grip portion (700) moves along the path with minimal friction without deviating from the path for positioning on the side of the cylindrical object (D).

[0093] In this way, the crucible transfer device (1) for a graphitizing furnace according to one embodiment can perform a stable grip operation by the grip portion (700) rotating in one direction or opposite direction around the central axis of the first support shaft portion (822) and the second support shaft portion (842) and contacting the cylindrical object (D).

[0094] In particular, if the gripper module (40) is eccentric and does not fit with the center of the cylindrical object (D), it can be fixed by accurately aligning it with the center of the cylindrical object (D).

[0095] In addition, if the center of gravity of the cylindrical object (D) changes or the attachment is abnormally connected, it is possible to prevent the accident in which the cylindrical object (D) is damaged or falls due to slip caused by poor contact.

[0108] And, a guide member (680) is attached to the lower side of the support bracket (610) to guide the movement so that the grip portion (700) moves along the path with minimal friction without deviating from the path for positioning on the side of the cylindrical object (D).

[0110] In particular, if the gripper module (40) is eccentric and does not fit with the center of the cylindrical object (D), it can be fixed by accurately aligning it with the center of the cylindrical object (D).

[0111] In addition, if the center of gravity of the cylindrical object (D) changes or the attachment is abnormally connected, it is possible to prevent the accident in which the cylindrical object (D) is damaged or falls due to slip caused by poor contact.

[0125] In addition, if the center of gravity of the cylindrical object (D) changes or the attachment is abnormally connected, it is possible to prevent the accident in which the cylindrical object (D) is damaged or falls due to slip caused by poor contact.

[0126] According to the embodiments, by moving plates (50a, 50b) on which gripper modules (40) are installed moving in a direction closer to or further away from base plates (50) on which gripper modules (40) are installed, it is possible to accurately grasp and move cylindrical objects (D) in a high-temperature environment, thereby significantly improving stability and efficiency.
