Problems solved by technology

However, in actual production activities, when the handling manipulator fails unexpectedly during operation and power or air is cut off, the double-acting cylinder 10' will carry the workpiece and suddenly fall out of control, causing damage to the workpiece and even a safety accident in severe cases.

Embodiment 1

[0028] Example 1: see figure 2 As shown, a safety protection method for a handling manipulator, the handling manipulator includes a double-acting cylinder 10, the handling manipulator performs up and down stroke movement under the drive of the double-acting cylinder 10, the first gas chamber 11 and the second air chamber of the double-acting cylinder 10 An external gas source supply circuit is provided between the gas chambers 12; the external gas source supply circuit includes an external air pressure source 21, and the external air pressure source 21 selectively injects air pressure into the first gas chamber 11 and the second gas chamber 12 through a multi-position five-way valve, Preferably, in this embodiment, the multi-position five-way valve adopts a two-position five-way valve 22, and the external air pressure source 21 is connected to an air pressure gauge 23; wherein, the safety protection methods include:

[0029] A first normally-off two-way valve 31 is provided b...

Embodiment 2

[0034] Embodiment 2: A handling manipulator, including a hydraulic cylinder, the handling manipulator moves up and down under the driving action of the hydraulic cylinder, the first hydraulic chamber and the second hydraulic chamber of the hydraulic cylinder are driven by a hydraulic supply circuit, and the hydraulic supply The circuit includes an external hydraulic source, and the external hydraulic source selectively injects hydraulic pressure into the first hydraulic chamber and the second hydraulic chamber through the two-position five-way valve; there is a first normally-off two-way valve between the two-position five-way valve and the first hydraulic chamber , and there is a second normally-off two-way valve between the two-position five-way valve and the second hydraulic chamber; state, the driving rod of the hydraulic cylinder performs vertical lifting movement under the switch control of the two-position five-way valve; The two-way valves are all in the power-off and ...

Abstract

The invention discloses a safety protection method for a carrying manipulator and the carrying manipulator. A first normally-closed two-way valve is arranged between a multiple position five-way valveand a first air cavity, and a second normally-closed two-way valve is arranged between the multiple position five-way valve and a second air cavity; when normal electrifying and ventilation are carried out, the first normally-closed two-way valve and the second normally-closed two-way valve are both in an electrified open state, a driving rod of a dual-functional air cylinder ascends and descendsvertically under the control of a switch of the multiple position five-way valve; and when accident power off or venting cessation occurs, the first normally-closed two-way valve and the second normally-closed two-way valve are both in a power-off closed state, so that a closed cavity body is formed between the first normally-closed two-way valve, the dual-functional air cylinder and the second normally-closed two-way valve so as to prevent abrupt change of air pressure in the first air cavity and the second air cavity, and the sudden drop of the carrying manipulator carrying a workpiece is avoided. According to the safety protection method for the carrying manipulator and the carrying manipulator, the hidden safety hazard of heavy object falling due to accident power off or venting cessation is eliminated, and a reliable guarantee is provided for safe carrying of the workpiece.

Description

technical field [0001] The invention relates to a safety protection technology for a handling manipulator, in particular to a safety protection method for a handling manipulator, and the invention also relates to a handling manipulator used in the safety protection method. Background technique [0002] With the rapid development and popularization of intelligent manufacturing, the application rate of handling manipulators in the actual production of enterprises is also considered to be an important indicator to measure the level of intelligent manufacturing of enterprises themselves. Specifically, in the automatic dicing machine equipment, the workpiece handling process mainly depends on the handling manipulator. Since the workpieces to be transported are very expensive, there are extremely high requirements for the stability and safety of the handling manipulator. [0003] Please see in particular figure 1 In the prior art shown in the external gas source supply circuit di...
