The 4.9 mechanical injury accident in Dongguan is a typical case.
At about 5:23 on April 9, 2022, Liu, an employee of a precision die casting co., LTD. in Dongguan City, accidentally squeezed his head by a machine mold while operating a die casting machine. Immediately after the scene personnel found out, they called ambulanceman. At 5:56, the ambulancemen arrived at the scene. However, the injured person has lost vital sign after the examination.
After investigation, the employee worked without safety education training. In the automatic mode of the die casting machine, he turned off the safety interlock device in violation of the law, and without cutting off the power supply, he probed into the mold cavity to operate, and was squeezed by the mold to death.
If the die casting machine is equipped with a smarter safety interlock or other emergency braking system, the probability of accidents will be much reduced. In view of similar situations, Vichnet proposed the safety protection solutions, always monitoring production safety, early warning of possible risks, emergency braking when encountering danger, and efficient response.
While optimizing and upgrading the original scheme, Vichent proposes targeted safety protection solutions for different production scenarios.
If the company applied the solution we proposed for the palletizing work unit before, once the instructions issued by system, inductive protective doors would open and interlocked to stop the dangerous operation of the equipment on the basis of the physical isolation of the fence, the safety control system such as safety switches, safety door locks, safety relays, etc..
when the robot arm is working, the person cannot enter the work area, or the robot arm is forced to lose power before the person enters, and the tragedy may be avoided.
