The distance L1 between the magnetic induction sensor 032 and the magnetic structure 031 can be set according to the maximum pressure that can be borne by the target object 04.

Specifically, referring to fig. 7, when the panel adsorbing device provided by the present invention is used to adsorb a panel, the lifting unit 02 connected to the outer tube 111 controls the suction rod 011 to descend to the surface of the target object 04, so that the suction cup 116 connected to the inner tube 112 is attached to the surface of the target object 04, so as to adsorb the target object 04, after the suction cup 116 contacts the surface of the target object 04, if the lifting unit 02 continues to control the outer tube 111 to descend, the spring 117 is compressed by the force of the spring 117, the spring 117 abuts against the end of the outer tube 111 close to the suction cup 116 and the suction cup 116, the pressure applied to the target object 04 includes the gravity of the inner tube 112 and the restoring force of the spring 117, and the distance L1 between the magnetic induction sensor 032 and the magnetic structure 031 can be measured according to the compression formula of the spring and the maximum pressure applied to. Therefore, after the distance L1 is set, in the process that the lifting unit 02 controls the suction rod 011 to descend to the surface of the target object 04, the distance L1 between the magnetic induction sensor 032 disposed on the outer tube 111 and the magnetic structure 031 disposed on the inner tube 112 is shortened, and if the pressure borne by the target object 04 does not exceed the maximum value of the pressure borne by the target object, the magnetic induction sensor 032 does not sense the magnetic structure 031; on the contrary, if the pressed degree of the target object 04 is too large, the magnetic induction sensor 032 will sense the magnetic structure 031, so as to early warn the pressed degree of the target object 04, and prevent the target object from being damaged due to too large pressed degree.
