[0019] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0020] Example: See Figure 1-3 In order to solve the problem that the current guardrail protection method cannot fully protect the working range, which is easy to cause personal safety of stray entry or maintenance personnel, a safety protection device between an industrial robot and a person is provided, including a base plate 1 and a robot body 2, characterized in that the robot body 2 is fixedly installed on one side of the upper end of the base plate 1, and a protection alarm structure is provided on the upper end of the base plate 1;

[0021] The protection alarm structure includes: two lateral guardrails 3, two fixed frames 4, a door body 5, a detection box 6, a detection plate 7 and a support alarm component;

[0022] The two lateral guardrails 3 are respectively fixedly installed on both sides of the upper end of the base plate 1, the two fixed frames 4 are respectively installed on one side of the upper end of the base plate 1, the two sides of the lower end of the door body 5 are respectively movably embedded in the two fixed frames 4, the detection box 6 is fixedly installed on the upper end of the base plate 1, the detection plate 7 is movably embedded in the upper end of the detection box 6, the support alarm component is fixedly installed in the detection box 6, and the top end is connected to the lower end of the detection plate 7.
