Pneumatic balancing mechanical arm

Abstract

The invention provides an air balanced manipulator and an air control system of the manipulator, which comprises a base, a pillar, a rotator, an operating arm and a fixture. The manipulator also comprises a main cylinder, a brake cylinder, a rotary joint, parallel four connecting rods of organizations, a rotary arm, a dead point braking mechanism and a pneumatic control system. The air control system comprises a gas source, an airway, a vacuum switch and a vacuum generator. The manipulator can balance the carried articles at any position of the movable and solid space and meet the demand of accurate and rapid assembly, with a portable and free operation. The air control system can control the movement of the manipulator by controlling the movement of the main cylinder and the brake cylinder, ensure that the manipulator does not drop to pose a risk when the gas source stops supplying gas for accidents and avoid that the carried articles drop for misoperation, thereby ensuring the safety of operators and products in maximum.

Description

technical field [0001] The invention relates to a transfer device, in particular to a pneumatic balance mechanical arm. Background technique [0002] The transfer device is a device used to carry or move items. Directly use the transfer device to move items instead of manual movement in the production process, which can greatly save human resources. Using the device to transfer articles in the process of conveying articles can reduce the physical labor of the operator, ensure the quality of the product, and improve the rationality of the operation. However, the current transfer devices are not flexible enough to move, and most of them can only be fixed at one position. The balance of the few movable transfer devices is not properly handled, which will cause unilateral force on the mobile device and cause safety hazards. The mechanical arm of the transfer device generally cannot move freely, some can move horizontally, and some can move up and down, but they cannot move both...

AI Technical Summary

Problems solved by technology

However, the current transfer devices are not flexible enough to move, and most of them can only be fixed in one position. A few movable transfer devices have not been properly handled due to the balance problem, which will cause unilateral force on the mobile device and cause potential safety hazards.

The mechanical arm of the transfer device generally cannot move freely, some can move horizontally, and some can move up and down, but they cannot move both horizontally and up and down

Moreover, during the movement of the mechanical arm of the transfer device, the horizontal state of the transported items cannot be guaranteed, causing deviations in the assembly position, making it difficult to install, and the quality of the product cannot be guaranteed.

At the same time, due to the unreasonable design of the mechanical arm of the transfer device, although the use of the mechanical arm to transport items saves time and effort compared with manual handling, the operator of the mechanical arm of the transfer device does not feel that the operation is very light and can do whatever he wants
