[0031] Track frame 11 extends from above tray frame 12 to above cutting device 40, and manipulator assembly 30 is slidingly installed on track frame 11, so that manipulator assembly 30 can reciprocate between tray frame 12 and cutting device 40, thereby realizing automatic feeding.Manipulator assembly 30 is provided with at least two negative pressure suction cups 31 distributed at intervals, which can adsorb and grab paperboard by using the principle of air pressure suction, to realize planar grabbing and carrying, and avoid scratches and bending of paperboard surface.The number of negative pressure suction cups 31 can be adjusted according to the adsorption area and adsorption force, for example, the number of negative pressure suction cups 31 can be set to two, four, six, eight, ten, twelve, etc.

[0032] In one embodiment, a single material tray 20 is provided, which is mounted on a tray frame 12 for storing cardboard. Preferably, the material tray 20 can slide telescopically along the tray frame 12 to facilitate material loading.

[0033] In another embodiment, two material trays 20 are provided, which are slidably mounted on the tray frame 12. Each material tray 20 can hold one type of cardboard, and two adjacent material trays 20 can hold two types of cardboard. The material trays 20 move along the tray frame 12 so that the corresponding processed material can be switched to the gripping position of the robotic arm assembly 30 as needed.

[0034] One of the material trays 20 moves and switches to the lifting direction of the robotic arm assembly 30. A negative pressure suction cup 31 is used to adsorb and grasp materials from the lower material tray 20. The robotic arm assembly 30 moves along the track frame 11 to place the materials into the processing area of ​​the cutting equipment 40. The device can accommodate two different types of cardboard or expand the capacity of the same type of cardboard.

The sensor can be a contact sensor or a non-contact sensor. For example, the sensor can be a pressure contact sensor, and the sensor is configured to output an electric signal when the bottommost paperboard presses the sensing end of the sensor, indicating that the material is out of stock.

[0039] The sensor can be a non-contact sensor. For example, the sensor can be a photoelectric sensor, and the sensor is configured to output an electric signal when the through hole 24 is out of paper, indicating that the material is out of stock.

[0040] Alternatively, the sensor can be mounted on the manipulator assembly 30 and can move with the manipulator assembly 30 to detect the paperboard in real time and determine whether the manipulator assembly 30 is clamped with the paperboard.
