Each vacuum suction cup 122 is arranged vertically, and its adsorption port is arranged on the side away from the fixing plate 121.

[0071] Please refer to Figure 1 , Figure 2 and Figure 9, the paper separating and sucking component 12 is movably arranged vertically below the paper separating cartridge 11 and is arranged to be turned over up and down. The paper separating and sucking component 12 includes a material sucking position and a material discharging position arranged in sequence from top to bottom on its vertical movement track. When the paper separating and sucking component 12 is at the material sucking position, the vacuum suction cup 122 faces the paper separating cartridge 11 and is located at the paper outlet 111; when the paper separating and sucking component 12 is at the material discharging position, the vacuum suction cup 122 faces away from the paper separating cartridge 11.

[0087] The working process of the material receiving device according to the preferred embodiment of the present utility model:

[0088] 1. In the initial state, the clamping jaws 1522 remain downward, and the material receiving module 15 is at a higher position. The feeding mechanism drives the material sheets to move to directly below the clamping jaws 1522. The vertical driving assembly 14 drives the material receiving module 15 to move downward to a position close to the material sheets, and the two groups of clamping jaws 1522 clamp the material sheets; the vertical driving assembly 14 drives the material receiving module 15 to move upward, and the feeding mechanism moves away; according to the orientation of the material sheets, the rotary cylinder 153 can drive the clamping assembly 152 to rotate 180° horizontally so that the orientation of each material sheet is the same. The vertical driving assembly 14 drives the material receiving module 15 to move downward to a position close to the material receiving box and releases the material sheets;

[0089] 2. During the process of the separator paper suction component 12 moving upward to the material suction position, it flips 180°, making the vacuum suction cup 122 face upward. The vacuum suction cup 122 turns on the suction force, sucks the bottommost separator paper in the separator paper cassette 11 through the paper outlet 111. Then, during the process of the vertical driving component 14 driving the separator paper suction component 12 to move downward to the material placement position, the rotation driving component 13 drives the separator paper suction component 12 to flip 180° so that the vacuum suction cup 122 faces downward. When the separator paper suction component 12 is at the material placement position, the vacuum suction cup 122 turns off the suction force, and the separator paper can be placed on the material sheet. After placing one separator paper, during the process of the vertical driving component 14 driving the separator paper suction component 12 to move upward, the rotation driving component 13 drives the separator paper suction component 12 to flip 180° so that the vacuum suction cup 122 faces upward and the clamping jaw 1522 faces downward;

[0090] 3. Place the material sheets and separator papers alternately according to the above steps.

[0091] In this way, the working process of the material receiving device of this preferred embodiment is completed.

[0092] For the separator paper suction component of the present utility model, the main negative pressure channel is connected to multiple first sub-channels, and the multiple first sub-channels are connected to multiple second sub-channels in one-to-one correspondence. Only need to connect the air extraction port to the vacuum pump, so that multiple vacuum suction cups can be controlled to turn on or off the suction force simultaneously by one vacuum pump, effectively reducing the cost; the air extraction port is located on the lateral side of the fixing plate, the first opening is located on the longitudinal side of the fixing plate, and the second opening is located on the vertical side of the fixing plate, so that the side of the fixing plate facing away from the vacuum suction cup can be connected to other structures without interference. The main negative pressure channel and multiple sub-negative pressure channels are all arranged inside the fixing plate, reducing the pipeline setting of multiple vacuum suction cups and reducing the volume of the entire separator paper suction component, thus making the structure of the separator paper suction component more compact.

[0093] For the automatic adsorption and placement mechanism of the separator paper of the present utility model, during its operation, the separator paper suction component is first at the material suction position. The vacuum suction cup turns on the suction force, sucks the bottommost separator paper in the separator paper cassette through the paper outlet. Then, during the process of the vertical driving component driving the separator paper suction component to move downward to the material placement position, the rotation driving component drives the separator paper suction component to flip 180° so that the vacuum suction cup faces downward. When the separator paper suction component is at the material placement position, the vacuum suction cup turns off the suction force, and the separator paper can be placed on the material sheet. After placing one separator paper, during the process of the vertical driving component driving the separator paper suction component to move upward, the rotation driving component drives the separator paper suction component to flip 180° so that the vacuum suction cup faces upward, and the separator paper suction component returns to the material suction position again to convey the next separator paper. The automatic adsorption and placement mechanism of the separator paper and the material receiving device of the present utility model can automatically move the separator papers in the separator paper cassette to the material sheets one by one, effectively improving the working efficiency and saving the labor cost.

[0094] The material receiving device provided by the utility model integrates the material receiving module on the paper separating suction component of the paper separating automatic adsorption and placement mechanism, and uses the vertical driving component of the paper separating automatic adsorption and placement mechanism to realize the lifting movement of the clamping component, so as to pick and place the material sheet. There is no need to set up the lifting driving mechanism for the clamping component, making the structure more compact and reducing costs.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the concept of the technical solution of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
