[0019] As shown in the drawings, Figures 1 to 6 in the present embodiment, the present application comprises a laminated stage 1, a conveying assembly 2 and a jacking and rotating assembly 3, a vacuum channel 101 is arranged in the laminated stage 1, a plurality of first suction holes 102 communicating with the vacuum channel 101 are arranged on the upper surface of the laminated stage 1, a vacuum breaking valve 103 and a vacuum one-way valve 104 are arranged at the bottom of the laminated stage 1, the vacuum breaking valve 103 and the vacuum one-way valve 104 both communicate with the vacuum channel 101, the conveying assembly 2 drives the laminated stage 1 to make reciprocating linear motion between the laminated station and above the jacking and rotating assembly 3, the jacking and rotating assembly 3 is positioned and matched with the laminated stage 1 and drives the laminated stage 1 to make directional adjustment action.

[0020] As shown in the drawings, Figure 4 and Figure 5As shown, in this embodiment, a vacuum connection block 105 is fixedly installed at the bottom of the stacked stage 1. The vacuum connection block 105 is provided with a conductive channel 106 communicating with the vacuum channel 101. The vacuum breaking valve 103 and the vacuum one-way valve 104 are both fixed on the vacuum connection block 105. The vacuum breaking valve 103 and the vacuum one-way valve 104 are both connected to the vacuum channel 101 through the conductive channel 106. The electronic ceramic vacuum rotary stage device also includes a vacuum assembly that cooperates with the vacuum breaking valve 103 and the vacuum one-way valve 104. The vacuum assembly is press-fitted with the trigger switch of the vacuum breaking valve 103. The vacuum assembly is connected to the vacuum one-way valve 104 and connected to an external vacuum pumping device. By setting the vacuum connection block 105, the vacuum breaking valve 103 and the vacuum one-way valve 104 are arranged side by side, which facilitates the connection to the vacuum pumping device and the breaking of the vacuum. Simultaneously, by sharing the conduction channel 106, the vacuum breaking valve 103 and the vacuum one-way valve 104 can be arranged more compactly, and both can act simultaneously on the vacuum channel 101. The vacuum breaking valve 103 is a micro-motion structure. Under external force, the internal chamber is compressed by a self-resetting piston, thereby generating a pressure change to break the vacuum. When the external vacuum equipment is started, the vacuum one-way valve 104 opens under negative pressure, thereby extracting the gas in the vacuum channel 101. When the external vacuum equipment stops, the valve automatically closes under the action of external pressure and a return spring. This ensures that the first adsorption holes 102 are always under negative pressure during transfer, and that the laminated product is firmly adsorbed onto the laminated platform 1 to maintain precise positioning.

[0021] like Figure 4 and Figure 5 As shown, in this embodiment, the stacking platform 1 is provided with two sets of vacuum connecting blocks 105. The two sets of vacuum connecting blocks 105 are located at a diagonal position on the stacking platform 1. Each set of vacuum connecting blocks 105 is provided with a vacuum breaking valve 103 and a vacuum one-way valve 104. The vacuum assembly is located on the side of the stacking station. By using two sets of vacuum connecting blocks 105, the vacuum channel 101 can be evacuated and broken before and after rotation, thereby improving the working efficiency of the equipment.

[0022] One implementation method, such as Figure 5As shown, the vacuum channels 101 connected by the two sets of vacuum connecting blocks 105 are independent of each other, thereby forming two independent negative pressure zones on the stacking platform 1. This structure ensures that even if one side of the negative pressure fails due to accidental vibration during the transfer process, the negative pressure on the other side can still guarantee that the stacked product is stably adsorbed on the stacking platform 1. Furthermore, during vacuum breaking, the weak vibration generated by vacuum breaking allows for the release of the stacked product by breaking the vacuum on one side.

[0023] In another embodiment, the two sets of vacuum connection blocks 105 share the same vacuum channel 101, which improves the efficiency of vacuuming and releasing.

[0024] like Figure 6 As shown, in this embodiment, the vacuum assembly includes a top-pressure cylinder 107, a trigger cylinder 108, and a vacuum connector 109. The movable end of the top-pressure cylinder 107 is equipped with a movable plate. Both the trigger cylinder 108 and the vacuum connector 109 are fixed to the movable plate. When the top-pressure cylinder 107 extends, the vacuum connector 109 engages with the vacuum one-way valve 104 and connects to an external vacuuming device for adsorption of the laminated products. When the top-pressure cylinder 107 retracts, the movable end of the trigger cylinder 108 extends and presses the trigger block of the vacuum breaking valve 103, reducing the negative pressure inside the vacuum channel 101 and thus releasing the adsorption of the laminated products. The top-pressure cylinder 107 drives the vacuum connector 109 to move linearly, thereby engaging with the vacuum one-way valve 104 to perform vacuuming, generating negative pressure in the first adsorption hole 102. The trigger cylinder 108 is a miniature cylinder; it extends to press the trigger block of the vacuum breaking valve 103 when vacuum breaking is required.
