Ceramic spacer rings are installed between the boats. After multiple coatings, the graphite boat needs to be disassembled regularly, and the card points on each boat need to be replaced before assembly. During the assembly process of the graphite boat, special automated equipment is required to carry out production and assembly operations.

[0003] For example, the Chinese patent "CN118335665A A graphite boat and boat sheet automatic assembly equipment" includes a ceramic spacer ring feeder, a ceramic rod divider, an assembly positioning mechanism, a first manipulator and a second manipulator. The ceramic spacer ring feeder is used to place ceramic spacer rings, the ceramic rod divider is used to separate and load the ceramic rods one by one, the assembly positioning mechanism is used to place and assemble the ceramic spacer rings and ceramic rods as well as the boat sheet and the nut according to the positional relationship, the first manipulator is used to move the ceramic rod from the ceramic rod divider to the assembly positioning mechanism, move the ceramic spacer ring from the ceramic spacer ring feeder to the assembly positioning mechanism, move the nut to the assembly positioning mechanism, and the second manipulator is used to move the boat sheet to the assembly positioning mechanism.

[0004] In the prior art, automatic assembly equipment for graphite boats and sheets usually adopts a robot-driven suction cup to adsorb and move the graphite boats and sheets for assembly. The position of the suction cup is customized according to the type of graphite boat and sheet, and is only applicable to this type of graphite boat and sheet assembly operation. When other special-shaped graphite boats and sheets need to be assembled, they need to be customized again, and the application effect is not good. Summary of the invention

[0005] The present invention relates to an automatic assembly device for graphite boats and sheets, which solves the problem that the existing automatic assembly equipment for graphite boats and sheets usually adopts a method of using a manipulator to drive a suction cup to perform adsorption and movement assembly operations on the graphite boats and sheets. The position of the suction cup is customized according to the type of graphite boat and sheet, and is only applicable to assembly operations of this type of graphite boat and sheet. When other special-shaped graphite boats and sheets need to be assembled, they need to be customized again, and the application effect is not good.

[0006] In a first aspect of the present disclosure, a graphite boat sheet automatic assembly device is provided, which specifically comprises: a main connecting member, a side connecting member, a bolt, a movable rotating arm, a transmission block, a transmission connecting rod, a screw, a suction cup, a central rotating shaft and a universal connector; the top of the main connecting member is fixedly connected to an assembly manipulator, and side connecting members are installed at both ends of the main connecting member, and two bolts are connected to the top of the main connecting member; the side connecting member is externally connected to two movable rotating arms, the two movable rotating arms are V-shaped with each other, and suction cups are installed at the ends of the movable rotating arms, the suction cups are connected to a negative pressure suction device through a pipeline, and the bottom of the suction cups is in contact with the graphite boat sheet; the bottom of the side connecting member is connected to a transmission block, and the transmission block is externally connected to two transmission connecting rods, the transmission connecting rods are connected to the movable rotating arms, and the transmission block is connected to the two movable rotating arms through the transmission connecting rod; the side connecting member is internally installed with a screw, and the screw is connected to the transmission block; the central rotating shaft is internally installed in the main connecting member, and universal connectors are installed at both ends of the central rotating shaft, the universal connector is located outside the main connecting member, and the universal connector is connected to the screw.

[0007] Furthermore, the movable rotating arm is rotatably connected to the side connecting piece, and a through hole is provided at the end of the movable rotating arm, and the suction cup slides through the through hole. The movable rotating arm can be rotated and adjusted according to the different types of graphite boat sheets to change the position of the suction cup, thereby better meeting the needs of adsorption, movement and assembly of different types of graphite boat sheets.

[0008] Furthermore, a spring is mounted on the outside of the suction cup, the bottom end of the spring contacts the suction cup, and the top end of the spring contacts the bottom of the movable rotating arm. When the bottom end of the spring contacts the graphite boat sheet, the spring is compressed, which protects the graphite boat sheet and prevents the graphite boat sheet from being broken due to excessive force. The spring makes the suction cup in close contact with the graphite boat sheet.

[0009] Furthermore, a guide groove is provided at the bottom of the side connecting member, and a slider is provided at the top of the transmission block. The slider is slidably connected to the guide groove provided in the side connecting member, and the sliding cooperation between the guide groove and the slider plays a guiding effect on the movement of the transmission block.

[0010] Furthermore, one end of the transmission connecting rod is rotationally connected to the transmission block, and the other end of the transmission connecting rod is rotationally connected to the movable rotating arm.

[0011] Furthermore, the screw is rotatably connected to the side connecting piece, a screw hole B is provided inside the transmission block, and the screw is threadedly connected to the screw hole B provided in the transmission block. By rotating the screw, the screw drives the transmission block to move, and the transmission block drives the two movable rotating arms to rotate synchronously through the transmission connecting rod, thereby changing the distance between the two suction cups.

[0012] Furthermore, the side connecting piece is rotatably connected to the main connecting piece, arc holes are provided at both ends of the main connecting piece, and a connecting ring is provided on the outside of the side connecting piece, which is slidably connected to the arc holes provided in the main connecting piece. According to the assembly requirements of a small number of special-shaped graphite boat pieces, the two side connecting pieces can be rotated to further change the position of the suction cup, increase the freedom of adjustment of the suction cup position, and better meet the requirements of adsorption and movement assembly of special-shaped graphite boat pieces.

[0013] Furthermore, a screw hole A is provided on the top of the main connecting member, and the bottom of the screw hole A is connected to the arc hole. The bolt is threadedly connected to the screw hole A provided on the main connecting member, and positioning grooves are arranged on the top of the connecting ring.

[0014] Furthermore, the central shaft is rotatably connected to the main connecting piece, and both ends of the central shaft are connected to two screws through a universal connector. The universal connector is located in the middle of the connection ring. After the rotation and adjustment of the two side connecting pieces are completed, the two universal connectors are adaptively adjusted accordingly. When one of the screws is rotated, the screw drives the central shaft to rotate through the universal connector, and the central shaft drives the other screw to rotate synchronously through the universal connector, so that the four movable rotating arms rotate synchronously, thereby ensuring the synchronization of the movement and adjustment of the four suction cups.

[0015] The present invention provides a graphite boat and sheet automatic assembly device, which has the following beneficial effects:

[0016] When the present invention is in use, the movable rotating arm can be rotated and adjusted according to the different types of graphite boat sheets, so as to change the position of the suction cup, thereby better meeting the needs of adsorption, movement and assembly of different types of graphite boat sheets. When the bottom end of the spring contacts the graphite boat sheet, the spring is compressed by force, which plays a protective effect on the graphite boat sheet to prevent the graphite boat sheet from being broken due to excessive force. The spring makes the suction cup closely contact with the graphite boat sheet to ensure the adsorption and fixing effect. Through the sliding cooperation between the guide groove and the slider, the transmission block is guided by the movement of the transmission block. The screw is rotated to drive the transmission block to move. The transmission block drives the two movable rotating arms to rotate synchronously through the transmission connecting rod, thereby changing the distance between the two suction cups and realizing the position adjustment effect of the pair of suction cups.

[0017] In addition, according to the needs of assembling a small number of special-shaped graphite boat pieces, the two side connectors can be rotated to further change the position of the suction cup, increase the freedom of adjusting the suction cup position, better meet the needs of adsorption and movement assembly of special-shaped graphite boat pieces, and have strong universal performance. After the rotation and adjustment of the side connector is completed, the screw hole A and the arc hole are in a connected state, and the bolt is rotated to move the end of the bolt into the positioning groove, and the side connector is fixed by the bolt to ensure the firmness of the connection between the side connector and the main connector.

[0018] In addition, after the two side connectors have been rotated and adjusted, the two universal connectors will be adaptively adjusted accordingly. When one of the screws is rotated, the screw drives the central shaft to rotate through the universal connector, and the central shaft drives the other screw to rotate synchronously through the universal connector, so that the four movable rotating arms rotate synchronously, ensuring the synchronization of the movement and adjustment of the four suction cups. There is no need to adjust them one by one, and the operation is easier.
