Embodiment 1

[0033] Refer Figures 1 to 9 As shown, this embodiment discloses a specific implementation manner of a blanking device for a graphite carrier assembly (hereinafter referred to as "blanking device").

[0034] The blanking device for the graphite carrier assembly, refer Figures 1 to 9As shown, the system includes a conveyor line 1, a robotic arm assembly 2, a flattening assembly 3, a suction cup assembly 4, a transfer platform 5, a graphite carrier hopper 6, a lower cover plate hopper 7, and an upper cover plate hopper 8. The conveyor line 1 transports the graphite carrier assembly 9 to a predetermined position. The robotic arm assembly 2 lifts the graphite carrier assembly 9 to the transfer platform 5. The suction cup assembly 4 picks up the upper cover plate 91 of the graphite carrier assembly 9 from the transfer platform 5 and places it into the upper cover plate hopper 8. The robotic arm assembly 2 picks up the material sheet 92 from the graphite carrier assembly 9 from the transfer platform 5 and places it into the flattening assembly 3, which flattens the material sheet 92. The suction cup assembly 4 picks up the lower cover plate 93 of the graphite carrier assembly 9 from the transfer platform 5 and places it into the lower cover plate hopper 7. The robotic arm assembly 2 lifts the graphite carrier 94 from the transfer platform 5 and places it into the graphite carrier hopper 6.

[0035] Specifically, the graphite carrier assembly 9 contains a material sheet 92, which is sintered from copper and ceramic sheets. The purpose of this embodiment is to unload the sintered graphite carrier assembly 9, i.e., to sequentially transfer the upper cover plate 91, the material sheet 92, the lower cover plate 93, and the graphite carrier 94 to predetermined positions, and to flatten the material sheet 92; see also... Figure 5 and Figure 6 The graphite carrier assembly 9 includes two parallel graphite carriers 94. Each graphite carrier 94 has a rectangular overall structure with a hollow interior. The bottom surface 941 and top surface 942 of each graphite carrier 94 are open. The bottom of each graphite carrier 94 has a vertical inner wall 943 forming a rectangle. A slope 944 exists between the bottom surface 941 and the top surface 942. A lower cover plate 93 is placed on the bottom surface 941 of the graphite carrier 94. A material sheet 92 is mounted on the slope 944 of the graphite carrier 94, and a first space 945 exists between the material sheet 92 and the lower cover plate 93. An upper cover plate 91 is placed on the top surface 942 of the graphite carrier 94. There is a second space 946 between the cover plate 91 and the material sheet 92. During the transfer, the suction cup assembly 4 first transfers the upper cover plate 91 into the upper cover plate hopper 8. Then, the robotic arm assembly 2 transfers the material sheet 92 into the flattening assembly 3, and the flattening assembly 3 begins the flattening operation. The suction cup assembly 4 transfers the lower cover plate 93 into the lower cover plate hopper 7, and the robotic arm assembly 2 simultaneously transfers the two graphite carriers 94 into the graphite carrier hopper 6. The flattening assembly 3, the suction cup assembly 4, and the robotic arm assembly 2 operate independently. While the material sheet 92 is being flattened, the transfer of the lower cover plate 93 and the transfer of the graphite carriers 94 can be carried out step by step without interfering with each other. Through parallel operation, the unloading operation of the graphite carrier assembly 9 is highly efficient.

[0036] See Figures 1 to 9The graphite carrier assembly 9 includes two graphite carriers 94 arranged side by side. The robotic arm assembly 2 can transfer the graphite carrier assembly 9 to the transfer platform 5 as a whole. The robotic arm assembly 2 includes a multi-degree-of-freedom robotic arm 21 and a transfer assembly 22. The end of the robotic arm 21 has a Z-direction degree of freedom and a Z-direction rotational degree of freedom.

Then, the robotic arm assembly 2 drives the transfer assembly 22 to rise. When the second vertical plate 225 and the third vertical plate 226 are aligned with the vertical inner wall surface 943 of the graphite carrier 94, the finger-clamping cylinder 224 drives the second vertical plate 225 and the third vertical plate 226 to move away from each other. When the upper ends of 225 and the third vertical plate 226 simultaneously abut against the vertical inner wall surface 943, the robotic arm assembly 2 drives the transfer assembly 22 to rise, simultaneously lifting the two graphite carriers 94, i.e., lifting the graphite carrier assembly 9, and then transferring the graphite carrier assembly 9 to the transfer platform 5 via the multi-degree-of-freedom robotic arm 21; the transfer platform 5 includes a first graphite carrier position 51 and a second graphite carrier position 52 arranged side by side, with the first graphite carrier position 51 and the second graphite carrier position 52 between them A support member 53 is provided, which allows the clearance part 229 to pass through, so that the robot arm assembly 2 can lift the graphite carrier assembly 9 from the bottom and place it in the first graphite carrier position 51 and the second graphite carrier position 52 of the transfer platform 5; after the material sheet 92 and the lower cover plate 93 are transferred respectively, the process of the robot arm assembly 2 transferring the two graphite carriers 94 is as follows: the robot arm assembly 2 adjusts the angle of the transfer assembly 22 so that the two second horizontal plates 223 are respectively aligned with the two graphite carriers from the top. After the graphite carrier 94 is lowered, the robotic arm assembly 2 drives the transfer assembly 22 to descend. When the second vertical plate 225 and the third vertical plate 226 are aligned with the vertical inner wall surface 943 of the graphite carrier 94, the finger-clamping cylinder 224 drives the second vertical plate 225 and the third vertical plate 226 to move away from each other. When the bottom ends of the second vertical plate 225 and the bottom ends of the third vertical plate 226 simultaneously abut against the vertical inner wall surface 943, the robotic arm assembly 2 drives the transfer assembly 22 to rise, thereby lifting the two graphite carriers 94.

[0038] See Figure 7 and Figure 8 The suction cup assembly 4 includes a horizontal moving module 41, a vertical moving module 42, a first suction cup 43, and a second suction cup 44. To accurately transfer the upper cover plate 91 into the upper cover plate hopper 8, the unloading device also includes a positioning platform 10. The suction cup assembly 4 first places the upper cover plate 91 on the positioning platform 10. The positioning platform 10 includes two fixed frames arranged at right angles and two movable frames arranged at right angles. The movable frames are driven by cylinders. Each upper cover plate 91 is driven by the two movable frames and abuts against the two fixed frames, so that the upper cover plate 91 is positioned in a fixed position, so that the suction cup assembly 4 can accurately pick up the upper cover plate 91 after it is positioned by the positioning platform and put it into the upper cover plate hopper 8.

Then, the first cylinder 341 and the second cylinder 351 are started to simultaneously press the material sheet 92 by the first downward pressing plate 343 and the second downward pressing plate 353 and keep the pressure for at least 5 s. After the pressure keeping is completed, the slide rail 32 drives the horizontal plate 33 carrying the material sheet 92 to move out like a drawer. Finally, the two flattened material sheets 92 are transferred to the material sheet storage bin 95 by the first negative pressure suction nozzle 227. Embodiment 2

Specifically, the robotic arm assembly 2 adjusts the angle of the transfer assembly 22 so that the two second horizontal plates 223 are aligned with the two graphite carriers 94 from the bottom. The robotic arm assembly 2 then drives the transfer assembly 22 to rise. When the second vertical plate 225 and the third vertical plate 226 are aligned with the vertical inner wall surface 943 of the graphite carrier 94, the finger-clamping cylinder 224 drives the second vertical plate 225 and the third vertical plate 226 to move away from each other.
