[0025] According to another embodiment of the utility model, the Bernoulli suction cup 13 further includes a connecting frame 14, a shell 15, a middle core assembly 16 and a proximity switch 17; the connecting frame 14 is fixed to the bottom end of the output rod of the telescopic cylinder 12, and is connected to the shell 15 by an adjusting bolt 18; a middle core assembly 16 is provided in the middle of the shell 15, a proximity switch 17 is installed on the top, and a plurality of groups of outer rubber rings are provided at the bottom of the shell 15.

[0026] According to another embodiment of the utility model, the middle core assembly 16 further includes a fixed shell 19, an outer core 20, an inner core 21 and a sealing ring 22; the outer core 20 is provided with an inner core 21, and the outside is fixed to the inside of the shell 15 by the fixed shell 19, a gap is provided between the outer core 20 and the inner core 21, an air inlet channel is provided in the middle of the inner core 21, and an air outlet hole is provided on the bottom side wall; one end of the air outlet hole is connected to the gap of the air inlet channel, and the upper end of the air inlet channel is threadedly connected to a quick-plug connector.

[0027] According to another embodiment of the utility model, the outer rubber ring is provided with a plurality of groups distributed circumferentially, and the proximity switch 17 is fixed to the top of the housing 15 between the two groups of adjusting bolts 18 through a connecting plate.

[0028] Specifically, when the proximity sensor of the proximity switch 17 contacts the casting to be transferred, the quick-connect connector is connected to the compressed air from the outside, and the air passes through the air inlet channel and the air outlet in turn into the gap between the outer core 20 and the inner core 21, and flows out through the guide plate at the bottom of the shell 15. At this time, the air flow velocity passing through the upper surface is greater than the air flow velocity at the lower part. According to the Bernoulli principle, when the fluid passes through a pipe or flows over the surface of an object, the flow velocity increases and the pressure decreases. At this time, a lifting force is gradually generated at the bottom, and the casting is adsorbed on the bottom of the Bernoulli suction cup 13. When the casting moves to the top of the carton, the compressed air stops flowing, and the casting falls from the bottom of the Bernoulli suction cup 13.

[0029] According to another embodiment of the utility model, the loading arm 10 is a fan-shaped structure, one end of the arc is connected to the output shaft of the rotating motor 9, and a plurality of groups of suction components 11 are installed at the bottom.

[0031] According to another embodiment of the present invention, guide baffles are further provided on both sides of the packaging conveying line 8 .

[0032] Specifically, the box enters the automatic box sealing and packaging machine 3 through the fixed position of the guide baffle, slides up and down through the support member 25, starts the box cover assembly 23 to fold the upper cover of the box, and then transports it to the bottom of the cover assembly 24 to stick the tape on the side wall of the front end of the box and compact it through the sealing roller. The conveyor belt moves so that the sealing roller moves along the movement direction of the box from the side wall of the front end of the box to the end side wall of the box, and then the cutting knife on the sealing roller cuts the tape to complete the packaging work.

[0033] The specific operation process is to start the automatic carton opener 2, the loading line 5 and the packaging line 6. The automatic carton opener 2 opens the carton and sends it to the vicinity of the loading mechanism 1 through the packaging line 6. The castings to be packaged are transmitted through the loading line 1. The loading mechanism 1 is started to adsorb several groups of castings on the loading line 1, rotate and put them into the carton. The operation is repeated several times until the carton is full. It is sent to the automatic carton sealing and packaging machine 3 through the packaging transmission line 8 for packaging and sealing, and finally transported to the vicinity by the palletizer 4 to wait for transportation.

[0034] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the appended claims, but all will fall within the scope of protection of the present invention.
