[0082] In some embodiments, the chuck 521 is a rubber or silica gel chuck.
[0083] Specifically, the chuck 521 can be made of rubber material in the form of a circular recess, and the bottom thereof is a recessed circular contact surface that can contact the surface of the adsorbed object.
[0084] The working principle of the chuck 521 adsorbing the font head is as follows: after the telescopic driving mechanism three 511 and the telescopic driving mechanism five 53 drive the chuck 521 to move downward and contact the surface of the font head, the air pressure pipe 522 sucks air into the chuck 521 to form negative pressure in the adsorption cavity, so that the air pressure in the chuck 521 is lower than the atmospheric pressure outside. Under the action of the air pressure difference, the chuck 521 is elastically deformed, and the circular recessed portion at the bottom thereof tightly contacts the surface of the object to form a sealed space. The atmospheric pressure outside will generate a uniform pressure on the chuck, tightly pressing the chuck against the surface of the object, thereby realizing the adsorption function. When the font head needs to be placed, the air pressure pipe 522 introduces positive pressure gas into the chuck, so that the chuck 521 is separated from the font head.
[0085] The electric control and the gas control system are combined, the electric control mechanical clamp jaw 31 is arranged at the lower end of the vertical shaft 1 2, the precise grabbing of the riser can be realized, the precise displacement and the opening and closing action can be realized, the fine requirements of the force and the position during the grabbing of the riser are met, the pneumatic telescopic mechanism realizes the up and down telescopic placement of the electromagnetic suction head 42 and the suction disc 521 on the vertical shaft 2 13 and the vertical shaft 3 14, the cold iron and the head are placed, the mobile base 1 is connected with the robot, the device is controlled by using the robot, the manual placing of the riser, the cold iron and the head on the wooden mold and other processes are replaced, and the specific working process is referred to Figure 3 .
